Product details
Overview
TPS55288RPMR from Texas Instruments is a synchronous four-switch buck-boost DC/DC converter IC with integrated 16-A MOSFETs on the boost leg, supporting input voltages from 2.7 V to 36 V and programmable output voltages from 0.8 V to 22 V in 20-mV steps. It delivers up to 100 W (e.g., 12 VIN → 20 VOUT/5 A), features ±1% reference accuracy, I²C interface, and average current-mode control - designed for USB Power Delivery (PD) compliant power supplies.
For engineers reviewing the TPS55288RPMR datasheet, TPS55288RPMR pinout, TPS55288RPMR application, or TPS55288RPMR equivalent, key selection criteria include its 26-pin VQFN-HR (4.0 mm × 3.5 mm) package, 200 kHz–2.2 MHz programmable switching frequency, ±5% output current monitoring accuracy, hiccup-mode short-circuit protection, and cable droop compensation via CDC pin.
Technical Context
The TPS55288RPMR employs average current-mode control with an internal error amplifier (transconductance = 190 µA/V) and programmable soft-start (4 ms typical). Its dual-mode operation-buck, buck-boost, or boost-automatically transitions based on VIN vs. VOUT relationship, enabling 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 clock synchronization via DITH/SYNC pin, and offers optional spread-spectrum EMI reduction. The I²C interface (100–1000 kHz) enables real-time configuration of output voltage, current limit (up to 6.35 A), and operating mode (PFM/FPWM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 36 V - supports wide-source applications including automotive battery, industrial rails, and USB PD adapters. |
| Output Voltage Range | 0.8 V to 22 V in 20-mV steps - enables precise PPS compliance and dynamic voltage scaling for diverse loads. |
| Max Output Current | 16 A average inductor current limit - set via ILIM pin resistor; supports high-power delivery without external current sense amplifiers. |
| Switching Frequency | 200 kHz to 2.2 MHz - adjustable via FSW pin resistor; allows optimization of size (high-freq) vs. efficiency (low-freq). |
| I²C Interface | Standard-mode/fast-mode plus (100–1000 kHz) - enables host MCU-based runtime reconfiguration of VOUT, IOUT limit, and protection thresholds. |

| Thermal Shutdown | 175 °C with 20 °C hysteresis - protects against sustained overload or poor PCB thermal design while enabling safe recovery. |
Pinout & Package
TPS55288RPMR is housed in a 26-pin VQFN-HR (RPM) package measuring 4.0 mm × 3.5 mm with exposed thermal pad. The leadless HotRod™ QFN construction minimizes parasitic inductance and improves EMI performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DR1L / DR1H | Buck-leg gate drivers | Drive external high-/low-side buck MOSFETs; require bootstrap capacitor (BOOT1–SW1) for high-side operation. |
| SW1 / SW2 | Switching nodes | SW1 connects to external buck-leg MOSFETs; SW2 connects to internal boost-leg MOSFETs - defines power path topology. |
| VIN / VOUT | Main power terminals | VIN accepts 2.7–36 V input; VOUT delivers regulated 0.8–22 V output - both rated for high-current PCB routing. |
| ISP / ISN | Current sense inputs | Measure output current via external sense resistor; enable ±5% accurate current limiting and monitoring via I²C registers. |
| FB/INT | Feedback/fault indicator | Configurable as voltage feedback node (external divider) or open-drain fault signal (e.g., OVP, thermal shutdown). |
| SCL / SDA | I²C serial interface | Enable full digital control: output voltage, current limit, mode selection, and status readback without analog component changes. |
| DITH/SYNC | EMI & sync control | Accepts external clock for synchronization or capacitor for spread-spectrum dithering - reduces peak EMI by >10 dB. |
| ILIM | Average current limit set | Resistor-to-ground sets 4–19 A average inductor current limit - critical for overcurrent protection in high-power USB PD designs. |

FAQ
What is the maximum continuous output current supported by the TPS55288RPMR?
The TPS55288RPMR supports up to 16 A average inductor current limit, set via an external resistor on the ILIM pin. This limit is independent of output voltage and applies across buck, buck-boost, and boost modes. Peak inductor current can reach 25 A under FPWM operation. Real-world continuous output current depends on thermal design, input/output conditions, and PCB layout - e.g., 5 A at 20 VOUT is achievable with proper heatsinking and 2-layer 2-oz copper.
Does the TPS55288RPMR support USB Power Delivery (PD) Programmable Power Supply (PPS)?
Yes, the TPS55288RPMR is explicitly designed for USB PD PPS compliance. It provides 20-mV output voltage resolution (0.8–22 V range) and 50-mA output current limit resolution via its I²C interface, meeting USB PD 3.0 PPS specifications. Cable droop compensation via the CDC pin further ensures terminal voltage accuracy during high-current delivery.
How is the switching frequency configured on the TPS55288RPMR?
The TPS55288RPMR switching frequency is set using an external resistor between the FSW pin and AGND, enabling adjustment from 200 kHz to 2.2 MHz. A 100 kΩ resistor yields ~200 kHz; a 9.09 kΩ resistor yields ~2.2 MHz. The device also supports external clock synchronization via the DITH/SYNC pin, allowing alignment with system clocks to avoid beat frequencies and EMI interference.
What protection features does the TPS55288RPMR include?
The TPS55288RPMR integrates output overvoltage protection (22.5–24.5 V threshold), hiccup-mode short-circuit protection, thermal shutdown (175 °C), cycle-by-cycle peak current limiting, and programmable average inductor current limiting. Fault status is reported via the FB/INT pin, which asserts low during OVP, thermal fault, or short-circuit events - enabling host MCU fault handling without additional sensors.
Can the TPS55288RPMR operate with only internal MOSFETs, or does it require external switches?
TPS55288RPMR integrates two 16-A MOSFETs on the boost leg but requires external MOSFETs on the buck leg - driven by DR1H and DR1L pins. This hybrid architecture balances efficiency, thermal performance, and flexibility: internal boost switches optimize high-voltage step-up, while external buck switches allow selection of optimal RDS(on) and thermal footprint for specific input voltage ranges.
