Product details
Overview
TPS552882RPMR from Texas Instruments is a synchronous four-switch buck-boost DC/DC converter with integrated 16-A boost-leg MOSFETs, operating across 2.7 V–36 V input and delivering regulated 0.8 V–22 V output. It supports seamless mode transitions (buck/boost/buck-boost), achieves 97% efficiency at 12 VIN/20 VOUT/3 A, and delivers up to 100 W from 12-V input-enabling USB PD power delivery in compact docking stations.
For engineers reviewing the TPS552882RPMR datasheet, TPS552882RPMR pinout, TPS552882RPMR application, or TPS552882RPMR equivalent, key selection criteria include programmable average inductor current limit (up to 16 A), ±1% reference voltage accuracy, 200 kHz–2.2 MHz adjustable switching frequency, spread-spectrum EMI reduction, and cable droop compensation via CDC pin.
Technical Context
The TPS552882RPMR employs average current-mode control for fast transient response, inherent line rejection, and simplified loop compensation using an external RC network on the COMP pin. Its dual-mode operation-programmable PFM for light-load efficiency or forced PWM for low-noise regulation-is selected via resistor on the MODE pin.
It integrates two 16-A boost-side MOSFETs (RDS(on) = 7.1 mΩ / 7.6 mΩ) and relies on external buck-side FETs, enabling flexible power stage optimization. Input UVLO (2.8 V rising / 2.65 V falling) and output OVP (23.5 V threshold) are internally fixed, while thermal shutdown activates at 175 °C with 20 °C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 36 V - supports wide-source applications including automotive battery (12 V nominal), industrial rails, and USB PD adapters. |
| Output Voltage Range | 0.8 V to 22 V - programmable via external resistor divider on FB pin with 1.2 V internal reference (±1% accuracy). |
| Max Output Current | 16 A average inductor current limit - set by resistor on ILIM pin; peak current limit up to 25 A protects during transients. |
| Switching Frequency | 200 kHz to 2.2 MHz - resistor-programmable on FSW pin; enables small magnetics and avoids AM band interference. |
| Efficiency | 97% at 12 VIN/20 VOUT/3 A - achieved via low-RDS(on) integrated MOSFETs and optimized gate drive (DR1H/DR1L). |
| EMI Mitigation | Programmable spread spectrum (±7%) and external clock synchronization - reduces peak radiated emissions without sacrificing regulation. |
| Protection Features | Output overvoltage (23.5 V), hiccup-mode short-circuit, thermal shutdown (175 °C), and programmable current limiting - ensures robust field operation. |
Pinout & Package
TPS552882RPMR is housed in a 4.0-mm × 3.5-mm, 26-pin VQFN-HR (HotRod™) package with exposed thermal pad. The leadless construction minimizes parasitic inductance and improves thermal performance (RθJA = 47.5 °C/W, RθJC(bot) = 7.8 °C/W).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| DR1L / DR1H | Buck-side gate drivers | Drive external high- and low-side MOSFETs in buck path; support synchronous rectification and high-efficiency step-down. |
| SW1 / SW2 | Switching nodes | SW1 connects to external buck FETs; SW2 connects to internal boost FETs - defines power path topology and layout critical zones. |
| VIN / VOUT / PGND / AGND | Power and ground terminals | VIN powers IC and high-side drivers; VOUT supplies load; PGND carries high-current return; AGND isolates sensitive analog circuitry. |
| FB / COMP / ILIM / DITH/SYNC | Control and configuration pins | FB sets output voltage; COMP hosts loop compensation; ILIM programs average current limit; DITH/SYNC enables spread spectrum or sync clock input. |
| EN/UVLO / MODE / PG / CC | Logic and status pins | EN/UVLO enables device and configures input lockout; MODE selects PFM/PWM and VCC source; PG signals valid output; CC indicates constant-current mode. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS55288RPMR | Same pinout and core architecture, but rated for 12-A average inductor current (vs. 16 A); lacks integrated boost FETs - requires external boost switches. | Suitable for ≤60-W designs where cost and board space outweigh peak current needs; not recommended for full 100-W USB PD. | Select TPS55288RPMR only when output current demand is ≤12 A and external boost FETs are acceptable for thermal or layout reasons. |
| MP2960GQ-Z | Monolithic 16-A buck-boost with 3.3–36 V input, but fixed 500-kHz switching and no spread spectrum; ±2% VREF accuracy vs. ±1%. | Targeted at cost-sensitive industrial SMPS; lacks CDC pin and cable compensation - unsuitable for USB PD PPS. | Choose MP2960GQ-Z for non-USB applications requiring simple, fixed-frequency 16-A conversion without EMI tuning or droop correction. |
Compared with TPS552882RPMR, TPS55288RPMR trades peak current capability and integration for lower BOM count in mid-power designs, while MP2960GQ-Z offers monolithic simplicity at the expense of precision regulation and EMI flexibility - making TPS552882RPMR the only choice for certified USB PD 3.1 PPS systems.

FAQ
What is the maximum continuous output current supported by the TPS552882RPMR?
The TPS552882RPMR supports up to 16 A of average inductor current, programmable via an external resistor on the ILIM pin. This rating assumes proper thermal management (e.g., 4-layer PCB with thermal vias to inner ground plane) and operation within recommended conditions (TJ ≤ 125 °C). Peak current limit reaches 25 A for transient overload protection.
Does the TPS552882RPMR integrate both buck and boost power MOSFETs?
The TPS552882RPMR integrates two 16-A MOSFETs on the boost leg (high- and low-side), but requires external MOSFETs for the buck leg (connected to DR1H/DR1L and SW1 pins). This hybrid architecture balances integration density, thermal dissipation, and design flexibility for high-power applications.
How does the TPS552882RPMR implement cable voltage droop compensation?
The TPS552882RPMR uses its ISP and ISN pins to sense output current, generating a proportional voltage fed to the CDC pin. An external resistor from CDC to AGND scales this signal to inject compensating voltage into the FB node - actively counteracting IR drop across USB-C cables without requiring host-side firmware intervention.
Can the TPS552882RPMR operate in forced PWM mode at light load?
Yes, the TPS552882RPMR can be configured for forced PWM (FPWM) mode at all loads by connecting a 0-kΩ resistor between the MODE pin and AGND. This disables pulse-frequency modulation, ensuring constant switching frequency - critical for noise-sensitive applications like audio or RF subsystems.
What thermal metrics apply to the TPS552882RPMR in its VQFN-HR package?
The TPS552882RPMR in the 4.0-mm × 3.5-mm VQFN-HR (RPMR) package has RθJA = 47.5 °C/W (standard JEDEC board) and RθJC(bot) = 7.8 °C/W. With proper PCB layout (2-oz copper, thermal vias under exposed pad), junction temperature rise remains within safe limits up to 125 °C ambient at full 16-A load.
