TPS65950A2ZXN - 3 DC/DC, 11 LDO PMIC | Texas Instruments
MPN： TPS65950A2ZXN ✓ 啟用中TPS65950A2ZXN 概覽
A power management IC is a semiconductor that controls and distributes electrical power to system loads. Within the hierarchy of power management semiconductors, this device combines DC/DC conversion, linear regulation, audio signal processing, USB connectivity, charging, LED driving, and analog conversion. That integration can reduce the number of separate components required around a portable processor, although the designer must still manage numerous rails and signal domains correctly.
The verified feature set includes three DC/DC converters and eleven LDOs. The integrated audio codec supports audio input and output functions, while the USB high-speed transceiver provides a high-speed USB interface. The device also includes an AC/USB charger, LED drivers, and an analog-to-digital converter, according to the manufacturer product page. These blocks make it relevant to embedded mobile, portable computing, and processor-based consumer platforms.
TPS65950A2ZXN operates from a 2.7 V to 4.5 V input range and is specified from -40°C to 85°C. Its 209-pin NFBGA package provides a high pin count for independent rails, grounds, control signals, and mixed-signal interfaces. Because the supplied source data does not enumerate individual rail currents, converter topologies, codec performance, USB data rates, or ADC resolution, those parameters should be confirmed in the manufacturer datasheet before final power-budget or signal-chain design.
Typical uses include OMAP-based mobile equipment, portable industrial terminals, connected embedded systems, and compact processor platforms requiring several regulated rails. In such systems, the PMIC can support processor core and peripheral power, audio capture or playback, USB connectivity, status indication, and battery-related power management. A system designer should treat rail sequencing, startup behavior, thermal performance, and high-current DC/DC layout as the primary implementation concerns.
The principal design trade-off is integration versus flexibility. One TPS65950A2ZXN can consolidate functions that might otherwise require several regulators, interface ICs, and passive networks, but its highly specialized 209-pin footprint and numerous configurable rails require careful reference-design review. PCB layout, exposed-pad thermal management, decoupling, and pin-compatible alternative validation are especially important because this is not a generic regulator package.
This page combines verified manufacturer and distributor information, package and temperature data, pricing dated October 29, 2026, same-family replacement screening, and practical design guidance. It also distinguishes confirmed drop-in candidates from unavailable cross-brand equivalents, helping engineers avoid assuming that a shared package category alone guarantees pin compatibility.

典型應用
TPS65950A2ZXN 適用於 6 應用s: OMAP Mobile Processor Platform, Portable Audio and Headset Equipment, USB-C and High-Speed Connectivity, Battery-Powered Embedded Terminal, Industrial Handheld and HMI, Connected Sensor and Edge Gateway.
OMAP Mobile Processor Platform
The TPS65950A2ZXN is a strong fit for an OMAP-class mobile processor because the verified device specification explicitly targets OMAP application processors. Its 3 DC/DC converters and 11 LDOs can organize a processor platform containing several core, I/O, memory, and peripheral rails, while the integrated audio codec and USB high-speed transceiver support two important platform interfaces. Operating from 2.7 V to 4.5 V aligns the device with portable power systems. The principal implementation requirement is to configure every rail and startup event against the TI reference design, since the supplied data does not identify individual output-current limits or sequencing timing.
推薦
Portable Audio and Headset Equipment
The integrated audio codec makes the TPS65950A2ZXN suitable for portable audio, headset, and voice-interface products that need to consolidate power regulation with sound conversion. The device operates from 2.7 V to 4.5 V and includes 3 DC/DC converters and 11 LDOs, allowing multiple low-noise rails to be managed in a processor-oriented design. Its -40°C to 85°C range covers many mobile and industrial environments. Engineers should verify codec resolution, signal-to-noise ratio, microphone biasing, headphone-drive capability, and analog grounding directly in the datasheet because those values were not included in the verified snippets.
推薦
USB-C and High-Speed Connectivity
The TPS65950A2ZXN can support compact products requiring both USB connectivity and tightly coordinated processor power. Its verified feature set includes a USB high-speed transceiver, while 3 DC/DC converters and 11 LDOs support the various rails normally found around an embedded processor. The 2.7 V to 4.5 V operating range is compatible with systems deriving power from a regulated single-cell source. USB design must be validated against the manufacturer reference circuit, including data-routing impedance, ESD protection, connector requirements, power negotiation, and exposed-pad thermal design; those implementation values were not supplied in the source data.
推薦
Battery-Powered Embedded Terminal
The TPS65950A2ZXN is appropriate for a battery-powered embedded terminal where one processor platform requires several voltage domains, audio functions, USB connectivity, status LEDs, and charging support. The manufacturer identifies an AC/USB charger and LED drivers alongside the 3 DC/DC converters and 11 LDOs, reducing the number of discrete blocks around the processor. Its 2.7 V to 4.5 V supply range and -40°C to 85°C operating range suit portable equipment. Final implementation requires charger-path review, battery chemistry compatibility, current-budget calculations, thermal analysis, and verification of every regulator's enable sequence against the official reference design.
推薦
Industrial Handheld and HMI
The TPS65950A2ZXN can serve as the central power and mixed-signal device in a processor-based industrial handheld or human-machine interface. The verified -40°C to 85°C rating covers typical industrial ambient conditions, while the 11 LDOs and 3 DC/DC converters support the multiple supply domains often required by a display controller, communications module, sensor interface, and processor. Integrated audio and USB functions reduce board area, but the 209-pin NFBGA package requires careful escape routing and inspection. Use the manufacturer layout guidance to control switching-node coupling, analog grounding, input transients, thermal vias, and rail sequencing.
推薦
Connected Sensor and Edge Gateway
The TPS65950A2ZXN is applicable to compact edge devices that combine an application processor, local sensing, USB service connectivity, audio feedback, and status indication. Its integrated 3 DC/DC converters and 11 LDOs simplify multi-rail distribution, and the 2.7 V to 4.5 V input range supports low-voltage portable architectures. The USB high-speed transceiver can reduce the need for a separate host interface, while LED drivers support local status feedback. Before implementation, confirm whether the gateway's processor current peaks and converter transient response align with the device limits, and confirm EMC, surge, and thermal requirements for the deployment environment.

- Matches the verified industrial ambient-temperature class (對比TPS65950BZXN)
設計說明
Build the complete power budget before assigning loads because the verified data identifies 3 DC/DC converters and 11 LDOs but does not provide individual current limits. Include processor startup peaks, audio load, USB current, charger input, and auxiliary rails, then add design margin to the manufacturer limits. Confirm the 2.7 V to 4.5 V operating range at the PMIC pins, including battery droop, cable loss, and worst-case transient conditions. Use the TI reference design for output capacitance, compensation, enable sequencing, and regulator mode settings rather than estimating those values from generic power-supply rules.
Treat the 209-pin NFBGA as a concentrated thermal design problem even though the verified operating-temperature specification is -40°C to 85°C. Estimate total dissipation from every enabled converter and LDO using the actual rail voltage, current, and efficiency assumptions, then compare the resulting junction-temperature estimate with the manufacturer limit. Provide a continuous ground plane, adequate thermal-via arrays beneath the exposed pad, and low-impedance copper paths to the board area. Do not substitute the package pin count for a measured thermal-resistance value because no verified junction-to-ambient resistance was provided.
Follow the manufacturer's PCB layout exactly for the ZXN 209-NFBGA footprint. Place input and output capacitors directly at the corresponding power balls, keep the exposed pad free of unintended plane isolation, and route sensitive audio, USB, and analog signals away from switching nodes. The supplied information does not include the complete ball map or recommended land pattern, so obtain both from TI before Gerber release. Validate the design with continuity checks and inspect a first article for accidental BGA opens, crossed rails, and thermal-via defects that are difficult to diagnose after assembly.
Do not assume that two devices in the TPS65950 family with 209-NFBGA packages are interchangeable. TPS65950BZXN matches the verified package, converter count, LDO count, and temperature range, but the supplied evidence does not confirm every ball function, accessory configuration, regulator setting, or USB behavior. Obtain both datasheets, create a pin-by-pin difference table, and compare startup sequences, electrical limits, exposed-pad connections, and exposed-software configuration. This check prevents a nominal drop-in candidate from causing an analog, charging, or power-sequencing failure.
合規資訊
The verified comparison data reports RoHS details for the TPS65950A2ZXN. No verified REACH, AEC-Q100, halogen-free, or conflict-minerals information was supplied; AEC-Q100 is shown as not applicable because the target is specified for mobile and OMAP applications rather than as an automotive-qualified variant.
