XRP7714ILBTR-SN01-F Présentation
A digital PMIC is a power management integrated circuit whose regulation loops, switching frequency, output voltage setpoints, protection thresholds, sequencing and timing are configured in firmware or non-volatile memory rather than by external analog component selection. The XRP7714 family sits in the hierarchy: PMIC > multi-output controller > digital PWM buck controller > power management IC for SoC systems, and replaces a board that would otherwise need several discrete switching controllers, an LDO, sequencers and supervisors.
Key features include a 4.75 V to 25 V input range, programmable switching frequency from 300 kHz to 1.5 MHz, integrated MOSFET drivers for synchronous buck stages, 6 GPIO/ENABLE pins with 3.3 V CMOS logic (5 V tolerant), and full on-chip protection (over-voltage, under-voltage, over-current, and thermal shutdown). Each rail is independently programmable for soft-start, ramp rate, sequencing and fault response, which makes the IC attractive as a one-chip power tree for FPGAs, DSPs and microprocessors.
The architecture is built on four independent Digital Pulse-Width Modulator (DPWM) channels with per-channel current-mode control loops, an internal reference and a precision LDO for standby/auxiliary rails. The integrated drivers and small 40-pin TQFN-EP footprint allow a 4-rail + LDO solution in roughly 25 mm x 25 mm of board area including passives, materially smaller than an equivalent analog implementation.
Typical applications are FPGA/SoC core and IO rails, networking and telecom boards, industrial controllers and embedded computing platforms where sequencing, monitoring and a small BOM matter more than absolute conversion efficiency. Designers choose this controller when rails must be re-configurable across SKUs or when a single PMIC replaces several discrete regulators.
When designing with this part, follow MaxLinear reference design guidance for output LC selection at the chosen switching frequency, place the IC on a thermally adequate copper pour, and use the GUI / I2C tools to program default output voltages and fault thresholds. The SN01-F suffix denotes a specific factory configuration and NVM image; verify the default output setpoints against the system requirements before re-programming in production.
This page combines verified distributor pricing, MaxLinear datasheet parameters, drop-in alternatives and practical design notes not gathered in any single manufacturer document, giving engineers a faster path from selection to qualified BOM.

Applications typiques
XRP7714ILBTR-SN01-F convient pour 6 applications: FPGA / SoC Multi-Rail Power Tree, Networking and Telecom Line Cards, Industrial Controller and Factory Automation, Embedded Computing Boards with DSP/Microprocessor, LED Driver and Display Backlight Power, Automotive Infotainment and ADAS Subsystems.
FPGA / SoC Multi-Rail Power Tree
The XRP7714ILBTR-SN01-F supplies the four core and IO rails plus one standby LDO of a typical FPGA or SoC power tree from a single 4.75-25 V intermediate bus, with each buck output programmable from 0.9 V to 5.1 V through I2C. Its integrated synchronous buck drivers and 1.5 MHz switching capability shrink the inductor footprint to roughly 1 uH per rail, while programmable soft-start and sequencing protect multi-rail FPGAs from latch-up. Compared to four discrete analog controllers plus a sequencer, the XRP7714 cuts BOM count by approximately 60% and provides I2C telemetry for fault monitoring in production.
Recommandé
Networking and Telecom Line Cards
The XRP7714ILBTR-SN01-F is well-matched to networking and telecom line cards that must accept a 12 V or 24 V backplane bus and generate four or five independent PoL voltages for switch ASICs, PHYs and PHYs' analog blocks. The 4.75-25 V input range covers typical -48 V telecom isolated intermediate bus voltages without a pre-regulator, and the integrated LDO can supply an always-on 3.3 V rail for management controllers. Programmable fault responses and GPIO-driven power-good signals simplify the design of OR-ing and hot-swap circuits required in NEBS-compliant systems.
Recommandé
Industrial Controller and Factory Automation
In industrial PLC and factory-automation boards the XRP7714ILBTR-SN01-F accepts 24 V nominal inputs (range 4.75-25 V) and generates the 5 V, 3.3 V, 1.8 V, 1.2 V and standby rails that feed a microcontroller, FPGA and analog front-ends. Programmable switching frequency from 300 kHz to 1.5 MHz lets designers move below the AM-band to ease CE/UL EMI compliance, while OVP/UVP/OCP/OTP protection supports the longer mission profiles of industrial equipment. The exposed-pad 40-pin TQFN simplifies thermal design with a single copper pour, important for sealed enclosures where ambient can reach 70 C.
Recommandé
Embedded Computing Boards with DSP/Microprocessor
The XRP7714ILBTR-SN01-F replaces multiple point-of-load regulators on DSP and microprocessor boards that need core, DDR, IO and analog rails sequenced from a common 5 V or 12 V input. The integrated LDO supports a low-current always-on rail for RTC and supervisory functions, and I2C programmability means one PCB design can target two or three processor SKUs simply by re-loading NVM. Compared to discrete regulators, the digital PMIC reduces quiescent power during light load, important for battery-backed industrial gateways.
Recommandé
LED Driver and Display Backlight Power
Although primarily a PMIC, the XRP7714ILBTR-SN01-F's four programmable buck channels can be re-purposed as constant-current LED drivers for medium-power LED strings when configured through I2C with external sense resistors. The integrated LDO supplies housekeeping logic for LED controllers and displays, and the wide input range simplifies driving 24 V LED strips from industrial or automotive buses. Programmable soft-start eliminates inrush that would otherwise require external FETs and PWM dimming inputs, reducing BOM cost per channel.
Recommandé
Automotive Infotainment and ADAS Subsystems
The XRP7714ILBTR-SN01-F can power infotainment and ADAS subsystems from a 12 V automotive bus (range 4.75-25 V covers load-dump-tolerant cold-crank to jump-start transients). Its 4 buck outputs feed an SoC's core, DDR, IO and analog domains while the LDO supplies a 3.3 V always-on rail for the microcontroller and CAN/LIN transceivers. I2C programmability enables SKU differentiation between infotainment variants without hardware rework, and on-chip OVP/UVP/OCP/OTP helps meet ISO 7637 and ISO 16750 transient expectations.

Notes de conception
The 40-TQFN-EP package relies on its exposed pad as the primary heat-dissipation path. Estimated: with 4 bucks each delivering 2 A at 80% efficiency from 12 V in, total dissipation is roughly 5 W. Place the IC on a top-layer copper pour of at least 25 mm x 25 mm with 9 thermal vias (0.3 mm drill, 0.6 mm pitch) directly under the EP to keep junction temperature rise below 35 C in still air. Without adequate copper, thermal shutdown (OTP) can trigger under full-load conditions.
Route the four LX switching-node traces as short as possible (ideally < 5 mm) and keep them over a continuous ground plane to minimize radiated EMI. Place input ceramic capacitors (one 22 uF + one 0.1 uF per buck) within 2 mm of the PGND/VIN pins. Avoid routing analog feedback (FB1-FB4) and I2C (SDA/SCL) traces parallel to LX traces; keep at least 3 mm spacing to prevent capacitive coupling that perturbs feedback accuracy.
Do not skip bootstrap capacitors on BST1-BST4; without these, the high-side MOSFETs of each buck will not turn on properly and the channel will fail to regulate. Ensure the VREF bypass capacitor (100 nF X7R) is placed within 1 mm of the VREF pin to AVSS, since this reference sets the accuracy of all four output voltages. Finally, when re-programming NVM through I2C, verify the part number suffix SN01 in your BOM matches the MaxLinear configuration tool output to avoid loading wrong rail setpoints.
Decouple the I2C lines (SDA, SCL) and GPIO pins with a small RC filter (100 ohm + 100 pF) if they are routed to noisy connectors, to prevent ESD or transient-induced I2C corruption. Place the ADDR pin to GND or VDD to select the desired I2C slave address before power-up; changing ADDR after the master ENABLE pin is asserted does not re-address the part. According to the MaxLinear programming guide, default slave address is 0x28 unless ADDR is strapped externally.
