Product details
Overview
TPS55288QWRPMRQ1 from Texas Instruments is an AEC-Q100 Grade 1 (–40°C to +125°C) synchronous four-switch buck-boost DC/DC converter with integrated 16-A boost-leg MOSFETs, I²C interface, and programmable output voltage (0.8 V–22 V) and current limit (up to 6.35 A). It delivers up to 100 W from 12-V input and supports USB Power Delivery (USB PD) Programmable Power Supply (PPS) in automotive infotainment and car charger systems.
For engineers reviewing the TPS55288QWRPMRQ1 datasheet, TPS55288QWRPMRQ1 pinout, TPS55288QWRPMRQ1 application, or TPS55288QWRPMRQ1 equivalent, key selection criteria include its 2.7–36-V input range, ±1% reference accuracy, 200 kHz–2.2 MHz programmable switching frequency, average current-mode control, and wettable-flank 4.0-mm × 3.5-mm VQFN-HR (RPM) package for automotive thermal and EMI robustness.
Technical Context
The TPS55288QWRPMRQ1 employs average current-mode control to enable stable regulation across buck, buck-boost, and boost modes-automatically transitioning based on VIN vs. VOUT relationship. Its dual 16-A internal boost-leg MOSFETs reduce external component count while maintaining high efficiency (97% at 12 VIN/20 VOUT/3 A).
It integrates I²C-configurable functions including output voltage (10-bit DAC), output current limit, cable droop compensation (CDC), spread spectrum, and mode selection (PFM/FPWM). Protection includes hiccup-mode short-circuit response, ±5% current monitoring, output overvoltage protection (22.5–24.5 V), and thermal shutdown at 175°C with 20°C hysteresis.

FAQ
What is the maximum output power supported by the TPS55288QWRPMRQ1?
The TPS55288QWRPMRQ1 delivers up to 100 W from a 12-V input (e.g., 20 V @ 5 A), enabled by its 16-A average inductor current limit, integrated 7.1-mΩ/7.6-mΩ boost-leg MOSFETs, and high-efficiency architecture (97% typical at 12 VIN/20 VOUT/3 A). Actual power depends on thermal design, PCB layout, and input/output conditions.
Does the TPS55288QWRPMRQ1 support USB PD Programmable Power Supply (PPS)?
Yes, the TPS55288QWRPMRQ1 fully supports USB PD 3.0/3.1 PPS via its I²C interface: output voltage is programmable from 0.8 V to 22 V in 20-mV steps, and output current limit is adjustable up to 6.35 A in 50-mA increments-meeting USB IF PPS specification requirements for dynamic voltage/current negotiation.
How does the TPS55288QWRPMRQ1 handle input voltage transients common in automotive systems?
The TPS55288QWRPMRQ1 operates across 2.7 V to 36 V input, covering cold-crank (down to 6 V) and load-dump (up to 36 V) events. Its EN/UVLO pin allows programmable undervoltage lockout, and built-in output overvoltage protection (22.5–24.5 V) safeguards downstream circuits during transients-ensuring robust operation per ISO 16750-2.
Can the TPS55288QWRPMRQ1 compensate for voltage drop across long USB cables?
Yes, the TPS55288QWRPMRQ1 implements active cable droop compensation via its CDC pin: it senses output current through ISP/ISN, generates a proportional voltage at CDC, and adds it to the feedback loop-enabling up to 750 mV of programmable VOUT boost to maintain target voltage at the device connector, critical for USB PD compliance.
What package options and thermal performance does the TPS55288QWRPMRQ1 offer?
The TPS55288QWRPMRQ1 uses the VQFN-HR (RPM) 26-pin package (4.0 mm × 3.5 mm) with wettable flanks for AOI compatibility. Its RθJA is 47.5°C/W (standard board) and 25.8°C/W (EVM), with RθJC(bot) = 7.8°C/W-enabling high-power operation in constrained automotive spaces when paired with proper copper pour and thermal vias.
