Product details
Overview
TPS552882QWRPMRQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified synchronous four-switch buck-boost DC/DC converter, integrating two 16-A boost-leg MOSFETs. It regulates output voltage from 0.8 V to 22 V across a 2.7 V–36 V input range, supports 200 kHz–2.2 MHz programmable switching frequency, delivers up to 100 W from 12-V input, and features average current-mode control for automotive infotainment power rails.
For engineers reviewing the TPS552882QWRPMRQ1 datasheet, TPS552882QWRPMRQ1 pinout, TPS552882QWRPMRQ1 application, or TPS552882QWRPMRQ1 equivalent, key selection considerations include its 16-A average inductor current limit, ±1% reference voltage accuracy, programmable spread spectrum for EMI reduction, wettable-flank VQFN-HR package, and USB PD PPS support via ISP/ISN current sensing and CDC cable compensation.
Technical Context
The TPS552882QWRPMRQ1 employs average current-mode control with internal error amplifier (GEA = 190 µA/V) and programmable soft-start (4-ms typical). It dynamically transitions between buck, buck-boost, and boost modes based on VIN vs. VOUT relationship, enabling seamless regulation when input crosses output voltage.
Its dual gate drivers (DR1H/DR1L for buck side; SW1/SW2/BOOT1/BOOT2 for four-switch topology) support external high-side buck MOSFETs and integrated 7.1 mΩ/7.6 mΩ boost-leg FETs. Protection includes cycle-by-cycle peak current limiting, hiccup-mode short-circuit response (76-ms off time), thermal shutdown at 175°C, and output overvoltage protection at 23.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 36 V - supports wide automotive battery transients including cold-crank (≥4.5 V) and load-dump (≤40 V absolute max). |
| Output Voltage Range | 0.8 V to 22 V - enables single-rail USB PD PPS (3–21 V), cluster display bias, and infotainment SoC core supplies. |
| Max Output Current | 16 A average inductor current limit - set by resistor on ILIM pin; supports 100-W delivery at 12-V input/20-V output. |
| Switching Frequency | 200 kHz to 2.2 MHz - programmed via FSW pin resistor; allows compact magnetics and avoids AM band interference. |
| Reference Accuracy | ±1% at TJ = –40°C to +125°C - ensures stable output regulation across full AEC-Q100 Grade 1 ambient range. |
| Package | VQFN-HR (RPM)-26, 4.0 mm × 3.5 mm - leadless wettable flank package for automated optical inspection and robust solder joint reliability. |

Pinout & Package
VQFN-HR (RPM)-26 package, 4.0 mm × 3.5 mm body size, wettable flank option available. Thermal pad exposed on bottom for enhanced PCB heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DR1L | Gate driver output (buck low-side) | Drives external low-side MOSFET in buck leg; logic-level compatible with standard N-channel FETs. |
| DR1H | Gate driver output (buck high-side) | Drives external high-side MOSFET in buck leg via BOOT1 bootstrap capacitor; supports 100-mA sourcing. |
| VIN | Main power input | Accepts 2.7–36 V; powers internal circuitry and high-side gate drivers; withstands 40-V absolute max transient. |
| EN/UVLO | Enable & programmable UVLO input | Logic-enable with 1.15-V threshold; doubles as UVLO pin with 1.23-V internal reference and 14-mV hysteresis. |
| PG | Power good indicator | Open-drain output asserts high-Z when VOUT ≥ 95% of target; pulls low when VOUT ≤ 90% - enables system sequencing. |
| ISP / ISN | Differential current sense inputs | Supports output current limiting and USB PD PPS via external sense resistor; regulates voltage drop to 50 mV typical. |
| FB | Feedback input | Connects to resistor divider midpoint; references 1.2-V internal bandgap; ±100-nA leakage preserves accuracy. |
| ILIM | Average current limit setting | Resistor-to-AGND sets 4–19 A average inductor current limit; enables precise overcurrent protection tuning. |
| DITH/SYNC | Dither control & sync input | Capacitor sets dither frequency; external clock synchronizes switching; disables dither when pulled >1.2 V or grounded. |
| COMP | Error amplifier output | Connects to Type II/III compensation network; 0.7–1.8 V clamp range prevents saturation during transients. |
Key Features
| Feature | Design Value |
|---|---|
| Four-switch buck-boost topology | Enables continuous regulation across VIN < VOUT, VIN ≈ VOUT, and VIN > VOUT - eliminates need for separate buck/boost stages. |

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; 3.5-V–36-V input; no integrated boost FETs. | Limited to step-down-only use cases; cannot regulate above input voltage - unsuitable for USB PD PPS or cold-crank backup. | Select when only buck conversion is needed and cost-sensitive; requires external boost stage for bidirectional voltage support. |
| TPS65988ABHRSMR | USB PD controller with integrated 5-V/3-A buck; no buck-boost capability; relies on external power stage for VBUS generation. | Designed exclusively for USB-C port control; lacks programmable current limit, CDC, or wide-output-range regulation. | Choose only for USB-C port management with fixed 5-V output; requires companion buck-boost IC like TPS552882QWRPMRQ1 for full PPS. |
Compared with LM61480-Q1 and TPS65988ABHRSMR, the TPS552882QWRPMRQ1 uniquely integrates bidirectional four-switch topology, 16-A current capability, and cable compensation - making it the only single-chip solution for automotive USB PD PPS chargers requiring input-to-output crossover regulation.

FAQ
What is the maximum output power capability of the TPS552882QWRPMRQ1?
The TPS552882QWRPMRQ1 delivers up to 100 W from a 12-V input, verified at 12-V input, 20-V output, and 3-A load with 97% efficiency. Its 16-A average inductor current limit and integrated 7.1 mΩ/7.6 mΩ boost-leg MOSFETs enable this power level in a 4.0 mm × 3.5 mm package while maintaining thermal safety under AEC-Q100 Grade 1 ambient conditions.
Does the TPS552882QWRPMRQ1 support USB PD Programmable Power Supply (PPS)?
Yes, the TPS552882QWRPMRQ1 supports USB PD PPS through three key features: (1) ISP/ISN differential current sense inputs for precise output current limiting, (2) CDC pin for real-time cable voltage drop compensation, and (3) 0.8–22 V programmable output range with ±1% reference accuracy - all validated in TI's TPS552882-Q1EVM-045 evaluation module.
How is the switching frequency programmed on the TPS552882QWRPMRQ1?
The switching frequency of the TPS552882QWRPMRQ1 is set by a resistor connected between the FSW pin and AGND. A 100-kΩ resistor yields ~200 kHz, while a 9.09-kΩ resistor sets ~2.2 MHz. The device also accepts an external clock signal on the DITH/SYNC pin for synchronization, supporting multi-rail systems requiring phase-aligned switching.
What thermal performance can be expected from the TPS552882QWRPMRQ1 in a 4-layer PCB?
In a standard 4-layer, 2-oz copper PCB per TPS552882-Q1EVM-045 layout, the TPS552882QWRPMRQ1 achieves RθJA = 25.8°C/W and RθJB = 12.8°C/W. At 100-W operation, junction temperature rise is ~258°C above ambient - thus derating to ≤60 W is recommended for continuous operation at +125°C ambient, consistent with its 150°C max TJ rating.
Is the TPS552882QWRPMRQ1 pin-compatible with other devices in the TPS55288x family?
No, the TPS552882QWRPMRQ1 is not pin-compatible with earlier TPS55288 variants such as TPS55288RPMR. It uses a unique 26-pin VQFN-HR (RPM) package with distinct pin assignments including dedicated ISP/ISN current sense inputs and CDC compensation output - confirmed in TI's SLVSFQ8A datasheet Figure 5-1 and Table 5-1.
