Product details
Overview
TPS55288QRPMRQ1 from Texas Instruments is an AEC-Q100 Grade 1 (–40°C to +125°C) synchronous four-switch buck-boost 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 TPS55288QRPMRQ1 datasheet, TPS55288QRPMRQ1 pinout, TPS55288QRPMRQ1 application, or TPS55288QRPMRQ1 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 architecture, and wettable-flank 4.0-mm × 3.5-mm VQFN-HR (RPM) package for automotive thermal and EMI robustness.
Technical Context
The TPS55288QRPMRQ1 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 pin), spread spectrum, and mode selection (PFM/FPWM). Protection includes hiccup-mode short-circuit response, ±5% current monitoring accuracy, output overvoltage protection (22.5–24.5 V), and thermal shutdown at 175°C with 20°C hysteresis.

Pinout & Package
VQFN-HR (RPM) 26-pin package with 0.4-mm pitch, 4.0-mm × 3.5-mm body, and wettable flank option for enhanced solder joint reliability in automotive reflow processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DR1L / DR1H | Buck-leg gate drivers | Drive external low/high-side buck MOSFETs; require bootstrap capacitor (BOOT1–SW1) |
| SW1 / SW2 | Switching nodes | SW1 connects to external buck FETs; SW2 connects to internal boost FETs - defines power path topology |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM61480-Q1 | Single-phase synchronous buck only (no boost capability); 8-A max output; no I²C interface | Limited to step-down-only automotive rails; cannot replace TPS55288QRPMRQ1 in USB PD or battery-voltage-crossing applications | Select when input always exceeds output and I²C configuration is unnecessary |
| MPQ4269-AEC1 | 4-switch buck-boost with 3.5-A continuous output; no integrated boost FETs; I²C support limited to voltage setting only | Lower power delivery; requires external boost MOSFETs and additional current-sense amplification for full PPS compliance | Select for cost-sensitive, lower-power infotainment accessories where full 6.35-A PPS is not required |
Compared with LM61480-Q1 and MPQ4269-AEC1, the TPS55288QRPMRQ1 uniquely combines 16-A internal boost FETs, full I²C configurability (voltage, current, droop, mode), and AEC-Q100 Grade 1 operation - making it the only single-chip solution for automotive USB PD 100-W chargers requiring no external high-current switches or firmware-level control loops.

FAQ
What is the maximum continuous output current supported by the TPS55288QRPMRQ1?
The TPS55288QRPMRQ1 supports a programmable output current limit up to 6.35 A in 50-mA steps via I²C register control. Its average inductor current limit can be set up to 19 A using the ILIM pin resistor, but sustained output current is constrained by thermal design, PCB layout, and input/output conditions. At 12-V input and 20-V output, it delivers 3 A at 97% efficiency per datasheet testing.
Does the TPS55288QRPMRQ1 support USB Power Delivery (USB PD) Programmable Power Supply (PPS)?
Yes, the TPS55288QRPMRQ1 is explicitly designed for USB PD PPS compliance. It offers programmable output voltage (0.8 V–22 V in 20-mV steps), programmable output current limit (up to 6.35 A), ±1% reference accuracy, and cable droop compensation - all controllable via I²C interface per USB PD 3.0 specification requirements.
What package type and mounting features does the TPS55288QRPMRQ1 use?
The TPS55288QRPMRQ1 uses the VQFN-HR (RPM) package: a 26-pin, 4.0-mm × 3.5-mm, 0.4-mm pitch leadless QFN with wettable flanks. This enables automated optical inspection (AOI) of solder joints - a critical requirement for automotive manufacturing quality assurance and long-term reliability under thermal cycling.
How does the TPS55288QRPMRQ1 handle input voltage transients common in automotive environments?
The TPS55288QRPMRQ1 operates across a 2.7-V to 36-V input range and includes programmable UVLO via the EN/UVLO pin (1.23-V internal reference, 8–20-mV hysteresis). It withstands load dump (up to 40 V absolute max) and cold-crank (down to 2.7 V) events without latch-off, and transitions seamlessly between buck, buck-boost, and boost modes to maintain regulation during battery voltage fluctuations.
Can the TPS55288QRPMRQ1 be synchronized to an external clock source?
Yes, the TPS55288QRPMRQ1 supports external clock synchronization via the DITH/SYNC pin. When driven with a logic-compatible square wave (VH ≥ 1.2 V, VL ≤ 0.4 V, tPW ≥ 50 ns), it locks its internal oscillator to the external frequency - eliminating beat frequencies and reducing EMI crosstalk in multi-converter systems such as automotive domain controllers.
