Product details
Overview
TPS552882QRPMRQ1 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, supporting 2.7 V to 36 V input and 0.8 V to 22 V output. It delivers up to 100 W from 12-V input, achieves 97% efficiency at 12 VIN/20 VOUT/3 A, and enables USB PD programmable power supply (PPS) via adjustable current limit and cable droop compensation. It is used in automotive infotainment systems requiring wide VIN/VOUT regulation across battery transients.
For engineers reviewing the TPS552882QRPMRQ1 datasheet, TPS552882QRPMRQ1 pinout, TPS552882QRPMRQ1 application, or TPS552882QRPMRQ1 equivalent, key selection criteria include its average-current-mode control architecture, 200 kHz–2.2 MHz programmable switching frequency with external sync capability, ±1% reference voltage accuracy, hiccup-mode short-circuit protection, and wettable-flank 4.0 mm × 3.5 mm VQFN-HR (RPM) package for automotive-grade reflow inspection.
Technical Context
The TPS552882QRPMRQ1 employs average current-mode control with internal error amplifier (GEA = 190 µA/V), enabling stable loop compensation and fast transient response. Its dual-mode operation-buck when VIN > VOUT, boost when VIN < VOUT, and alternating buck/boost near crossover-ensures seamless regulation across wide input/output differentials.
It integrates two 16-A boost-leg MOSFETs (RDS(on) = 7.1 mΩ low-side, 7.6 mΩ high-side), supports external resistor-set average inductor current limit (4–19 A), and provides programmable PFM/FPWM light-load modes via MODE pin resistor selection. Spread spectrum (±7%) and clock synchronization on DITH/SYNC further reduce EMI without compromising regulation.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS55288QRPMRQ1 | Same pinout and feature set but rated for 12-A continuous output (vs. 16-A); lower average current limit (12 A vs. 16 A); identical 2.7–36 V input and 0.8–22 V output ranges | Suitable for ≤100-W applications where peak current demand is below 12 A; not recommended for sustained 16-A loads or high-temperature environments requiring full derating margin | Select TPS55288QRPMRQ1 only if system peak current remains ≤12 A and thermal headroom permits - verify ILIM resistor value matches reduced limit |
| LM61480QRPHRQ1 | 36-V, 8-A synchronous buck-only converter; no boost capability; fixed 5-V or adjustable 0.8–20 V output; lacks USB PD PPS features (ISP/ISN, CDC) | Applicable only where input always exceeds output (e.g., 12 V → 5 V); cannot regulate during battery brownout (VIN < VOUT) or support USB PD voltage negotiation | Choose LM61480QRPHRQ1 only for fixed-step-down applications with ample VIN margin - not a functional substitute for buck-boost or PPS use cases |
Compared with TPS55288QRPMRQ1, the TPS552882QRPMRQ1 delivers 33% higher continuous current capability and full USB PD PPS support, while LM61480QRPHRQ1 offers simpler buck-only regulation but no voltage-up capability or current-programming interface - making TPS552882QRPMRQ1 uniquely suited for automotive USB-C charging and adaptive infotainment power rails.
