TPS65219CRSLR Обзор
What is a PMIC? A Power Management IC (PMIC) is a highly integrated device that consolidates multiple voltage regulators (typically buck converters and LDOs) into a single silicon die. The PMIC sits hierarchically above individual voltage regulators in the power-distribution tree of an SoC, sitting between the battery or DC bus and the core, memory, and I/O rails of the processor. By integrating sequencing, monitoring, and protection, a PMIC reduces PCB area, simplifies BOM, and improves reliability compared to discrete regulator designs.
Key features of the TPS65219CRSLR include wide input voltage support, dynamic voltage scaling for adaptive energy saving, I2C-configurable output voltages, and integrated protection such as over-current, over-temperature, and under-voltage lockout. The device supports power-button input, reset output, and a dedicated processor interface, making it suitable for plug-and-play power tree designs with TI Sitara AM62x / AM62Ax family processors.
The architecture uses three synchronous buck converters with internal MOSFETs to deliver high efficiency across light and heavy load conditions, complemented by four low-dropout regulators for analog and auxiliary rails. Built-in sequencing logic coordinates rail startup and shutdown to match SoC requirements, while an I2C interface enables software control of output voltages and operating modes.
Typical applications include building automation, factory automation and control, industrial HMI panels, handheld terminals, and FPGA-based embedded vision systems. The compact VQFN-48 (RSL) package and industrial temperature range (-40C to +105C) make the TPS65219CRSLR especially well-suited to ruggedized embedded applications requiring high integration.
When designing with this PMIC, follow the manufacturer reference layout in the datasheet and ensure the exposed thermal pad is soldered to a sufficient copper pour for thermal dissipation. Decoupling capacitors must be placed close to each buck/ldo output pin per the datasheet application circuit to ensure loop stability.
This page synthesizes verified distributor pricing, drop-in pin-compatible alternatives, and practical design notes that complement the official manufacturer datasheet, helping engineers evaluate sourcing, second-source, and PCB-layout decisions for the TPS65219 family.

Типичное применение
TPS65219CRSLR подходит для 6 применениеs: Industrial HMI Panels, Building Automation Controllers, Factory Automation and Control, Handheld Terminals and Portable Devices, FPGA-Based Embedded Vision Systems, Smart Appliance Control Boards.
Industrial HMI Panels
The TPS65219CRSLR is well suited for industrial Human-Machine Interface (HMI) panels built around AM62x / AM62Ax Arm Cortex-A53 SoCs. Its three synchronous buck converters deliver high-efficiency core and DDR rails while four LDOs supply analog touch-controller, audio codec, and I/O domains. The I2C interface allows the SoC to dynamically adjust voltages during light-load operation, extending panel backlight uptime. Industrial -40C to +105C operation supports factory-floor deployment, and the integrated UVLO/OCP/OTP protection ensures reliable long-life behavior.
Рекомендуется
Building Automation Controllers
Building automation controllers (HVAC, lighting, access control) benefit from the TPS65219CRSLR's all-in-one power tree. The PMIC generates core, memory, and I/O rails from a single 5V input, eliminating multiple discrete regulators on the controller board. The I2C programmability lets a single PCB design support multiple SoC variants by reconfiguring output voltages. With industrial temperature grade and integrated protection, the TPS65219CRSLR is a drop-in power solution for wall-mounted smart-building controllers.
Рекомендуется
Factory Automation and Control
Factory automation PLCs, motor controllers, and machine-vision terminals require ruggedized power with deterministic sequencing. The TPS65219CRSLR's integrated sequencing matches AM62x power-on requirements, while its OCP/OTP/UVLO protections safeguard against field faults. The VQFN-48 package with exposed pad provides thermal headroom for the 105C industrial ambient. I2C control enables firmware-driven power-state management during duty-cycled operation, reducing energy use in always-on factory cells.
Рекомендуется
Handheld Terminals and Portable Devices
Handheld data terminals, barcode scanners, and portable diagnostic devices benefit from the TPS65219CRSLR's small footprint and low quiescent current. Three high-efficiency bucks reduce battery drain on the main rails, while the four LDOs supply low-power analog blocks. The integrated sequencing enables clean rail-up from a battery or USB-Powered input. Industrial temperature grade supports outdoor and warehouse usage, and the VQFN-48 7x7 mm footprint keeps the PMIC smaller than the SoC it powers.
Рекомендуется
FPGA-Based Embedded Vision Systems
FPGA-based smart-camera and embedded-vision designs often require multiple precisely sequenced voltage rails. The TPS65219CRSLR supplies FPGAs with three buck rails (core, auxiliary, DDR) plus four LDOs for transceivers and analog sensors. I2C configurability lets designers tune rail voltages to match FPGA speed grades or power-down unused banks. The industrial temperature range and exposed-pad VQFN-48 package suit vision modules deployed in industrial enclosures.
Рекомендуется
Smart Appliance Control Boards
Smart appliances (refrigerators, washers, ovens) integrate display, connectivity, and sensor subsystems on a single control board. The TPS65219CRSLR provides all voltage rails for an AM62x-based control board from a 12V/5V input, simplifying BOM and reducing PCB area. The I2C interface enables the appliance firmware to dynamically lower core voltage during idle, saving standby power. Industrial temperature rating supports kitchen and laundry environments, and the integrated protections guard against motor-induced voltage transients.

- Industrial -40C to +105C temperature range (против TPS65220CRSLR)
Заметки по проектированию
The exposed thermal pad of the VQFN-48 package MUST be soldered to a top-layer ground pour with thermal vias to inner ground planes. Estimated: with a 4-layer PCB and 6 thermal vias, the resulting theta_JA is approximately 25-30 C/W, allowing the PMIC to dissipate up to 2W safely at 105C ambient. Without the EP soldered, junction temperature rises rapidly and the device may trigger OTP shutdown.
Place input bulk capacitors (>= 22uF) as close as possible to each VIN pin, and add 100nF ceramic bypass capacitors directly at each VIN pin. Per TI reference layouts, the buck output capacitors (typically 22-47uF ceramic) must be placed within 2-3 mm of the SW node to minimize switching loop area and reduce EMI. Estimated: a switching loop area under 0.5 cm^2 keeps peak EMI below CISPR 22 Class B limits.
At maximum load on all three bucks plus four LDOs, the TPS65219CRSLR can dissipate 1.5-2W of power. In a sealed enclosure at 85C ambient, this may push junction temperature close to the 125C limit. Estimated: with theta_JA of 28 C/W on a well-designed 4-layer PCB, junction rises 42-56C above ambient. Use thermal vias under the EP and ensure adequate airflow in the enclosure.
Do not assume any TPS65219 suffix variant (CRSLR, CRHLR, RSLR) is pin-compatible - the datasheet pinout section must be cross-checked before substituting. The I2C address is fixed; if multiple TPS65219 devices are used on the same I2C bus, ensure the bus is segmented or address-strap configuration is verified. Also, the power-button input has an internal pull-up; an external debounce capacitor of 1nF-100nF is recommended to prevent false triggers.
