Product details
Overview
TPS54880PWPR from Texas Instruments is a 4-V to 6-V input, 8-A output synchronous buck PWM converter with integrated high- and low-side MOSFETs (30 mΩ typical), tracking capability via TRACKIN pin, fixed/adjustable switching frequency (350 kHz default or 280–700 kHz), and Power Good output - designed for sequencing power rails in FPGA and microprocessor point-of-load applications.
For engineers reviewing the TPS54880PWPR datasheet, TPS54880PWPR pinout, TPS54880PWPR application, or TPS54880PWPR equivalent, this page delivers verified specifications, validated thermal package details (28-pin PWP PowerPAD™), real-world sequencing use cases, and two confirmed alternative parts with documented functional and layout implications.
Technical Context
The TPS54880PWPR implements a voltage-mode PWM control architecture with an internal 0.891-V precision reference, wide-bandwidth error amplifier (90–110 dB open-loop gain, 3–5 MHz unity-gain bandwidth), and adaptive dead-time logic to prevent shoot-through. Its TRACKIN pin enables precise power-up/down sequencing by synchronizing with external regulators' enable or feedback signals.
It integrates dual 30-mΩ (VI = 4.5 V) MOSFET switches, supports continuous 8-A output current with peak 12-A capability, and features under-voltage lockout (3.8 V start / 3.5 V stop), thermal shutdown (135–165 °C trip), and cycle-by-cycle peak current limiting (9–12 A trip point).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.0 V to 6.0 V - matches standard 5-V intermediate bus; UVLO prevents startup below 3.8 V. |
| Continuous Output Current | 8 A - sustained delivery without derating at TJ ≤ 125 °C with proper PCB thermal design. |
| Switching Frequency | Fixed 350 kHz or adjustable 280–700 kHz via RT resistor - enables EMI optimization and inductor size tradeoffs. |
| Output Voltage Accuracy | ±1% over temperature - achieved via 0.891-V trimmed reference and high-precision error amplifier. |
| Integrated MOSFET RDS(on) | 30 mΩ (high-side & low-side, VI = 4.5 V) - reduces conduction loss and eliminates external FET layout complexity. |
| Thermal Protection | 135–165 °C shutdown with 10 °C hysteresis - prevents permanent damage during overload or poor heatsinking. |
| Power Good Threshold | 90% of Vref (0.802 V) with 3% hysteresis - provides reliable reset signaling for processors and FPGAs. |
Pinout & Package
The TPS54880PWPR is housed in a thermally enhanced 28-pin HTSSOP (PWP) PowerPAD™ package measuring 6.4 mm × 9.7 mm, with an exposed thermal pad soldered directly to PCB ground for efficient heat dissipation - no external heatsink required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AGND (Pin 1) | Analog ground reference | Return path for compensation network, VBIAS capacitor, RT resistor; must connect to PowerPAD and isolated analog ground trace. |
| VSENSE (Pin 2) | Error amplifier inverting input | Connects to output divider; senses regulated voltage with ±1.5 mV offset vs TRACKIN for tracking accuracy. |
| COMP (Pin 3) | Error amplifier output | Drives external Type 2/3 compensation network; 1.0–1.4 V/µs slew rate supports stable loop response. |
| PWRGD (Pin 4) | Open-drain power-good indicator | Sinks 2.5 mA at ≤0.3 V when VSENSE ≥ 90% Vref - used for processor reset or system enable sequencing. |
| BOOT (Pin 5) | Bootstrap gate drive supply | Requires 0.022–0.1 µF ceramic capacitor to PH; enables high-side FET drive above VIN. |
| PH (Pins 6–14) | Phase node (switching node) | High-current connection to inductor; 9 pins paralleled to reduce resistance and thermal stress at 8-A load. |
| RT (Pin 28) | Oscillator frequency set input | Resistor to AGND sets frequency: open = 350 kHz; 68 kΩ = ~700 kHz; 180 kΩ = ~280 kHz. |
| ENA (Pin 27) | Enable control input | Logic-high ≥1.4 V enables operation; hysteresis (0.03 V) and 2.5 µs deglitch prevent false triggering. |
| TRACKIN (Pin 26) | External tracking reference input | High-impedance input accepts external voltage ramp; enables simultaneous power-up/down with other rails. |
| VBIAS (Pin 25) | Internal bias regulator output | 2.70–2.90 V supply for internal circuitry; requires 0.1–1.0 µF ceramic bypass to AGND. |
| VIN (Pins 20–24) | Main input power supply | Five parallel pins minimize IR drop; each requires local 10-µF ceramic bypass to PGND. |
| PGND (Pins 15–19) | Power ground return | High-current return for low-side FET and input/output capacitors; separate from AGND except at PowerPAD. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 30-mΩ MOSFETs | Eliminates external high-side/low-side FETs and drivers, reducing BOM count and PCB area by >30% vs controller-based solutions. |
| TRACKIN-enabled sequencing | Supports precise power-up/down coordination between core and I/O rails without external timing ICs or discrete logic. |
| PowerPAD™ thermal package | 28-pin PWP with exposed copper pad achieves 18.2 °C/W θJA (with solder); enables 8-A operation without heatsink on 3″×3″ 4-layer board. |
| Adjustable 280–700 kHz frequency | Allows EMI spread-spectrum tuning and optimization of inductor size/cost while maintaining >90% efficiency at full load. |
| True voltage-mode error amplifier | 90–110 dB open-loop gain and 3–5 MHz bandwidth support robust stability with diverse L-C filter combinations (e.g., 0.65 µH + 66 µF). |
| Comprehensive protection suite | Includes cycle-by-cycle current limit (9–12 A), thermal shutdown (135–165 °C), UVLO (3.8 V start), and PWRGD monitoring - no external fault management needed. |
Applications
| FPGA Core Rail Sequencing | ASIC I/O Supply Regulation |
|---|---|
Use Scenario: Powering 1.2-V core rail of Xilinx Kintex-7 FPGA with strict <100-µs power-up delay relative to 1.8-V I/O rail. IC Role / Device Role / Timing Role: Primary buck regulator generating core voltage; TRACKIN pin synchronized to I/O supply's PWRGD signal to enforce monotonic ramp alignment.

Use Value: Ensures I/O voltage never exceeds core voltage during power-down, preventing latch-up per JEDEC JESD8-12. |
| Networking ASIC Point-of-Load | Optical Transceiver Bias Supply |
Use Scenario: Regulating 0.9-V, 8-A supply for Broadcom BCM84892 100G Ethernet PHY under 85 °C ambient.

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS54821RHLR | Same 28-pin QFN (RHL) package; 30-mΩ FETs; 0.6-V to 5.5-V input; 6-A continuous output; no TRACKIN pin. | Lacks dedicated tracking functionality - requires external comparator or sequencer for multi-rail coordination. | Choose when sequencing is handled externally and smaller footprint (5 mm × 6 mm vs 6.4 mm × 9.7 mm) is critical. |
| LM27402SDX/NOPB | 16-pin WQFN; controller-only (external FETs); 4.5–20-V input; up to 15-A output; no integrated tracking circuitry. | Requires external MOSFETs, gate drivers, and sequencing logic - higher BOM cost and layout complexity. | Prefer when input voltage exceeds 6 V or when programmable current limit and phase interleaving are needed. |
Compared with TPS54880PWPR, TPS54821RHLR offers identical thermal performance in a smaller QFN but sacrifices TRACKIN-based sequencing, while LM27402SDX/NOPB provides wider input range and higher current scalability at the cost of added external components and no native tracking support.

FAQ
What is the maximum continuous output current supported by the TPS54880PWPR?
The TPS54880PWPR supports 8-A continuous output current under recommended operating conditions (TJ ≤ 125 °C, proper PCB thermal design with PowerPAD soldered to ≥3″×3″ 1-oz copper plane). Peak current capability reaches 12 A before cycle-by-cycle current limit activation, as confirmed in the Electrical Characteristics table (current limit trip point: 9–12 A).
How does the TRACKIN pin function in the TPS54880PWPR?
The TRACKIN pin on the TPS54880PWPR is a high-impedance input that accepts an external voltage ramp to synchronize power-up/down timing with another regulator. When TRACKIN rises slower than the internal 25 V/ms slope, the TPS54880PWPR output follows it; once TRACKIN exceeds 0.891 V, the internal reference takes over. This enables precise rail sequencing without external timers or comparators.
What package type and thermal characteristics define the TPS54880PWPR?
The TPS54880PWPR uses a 28-pin HTSSOP (PWP) PowerPAD™ package measuring 6.4 mm × 9.7 mm with an exposed thermal pad. With proper PCB layout (12 thermal vias, 3″×3″ analog ground plane), its junction-to-ambient thermal resistance is 18.2 °C/W, enabling 5.49 W power dissipation at TA = 25 °C - sufficient for 8-A operation without heatsink.
Can the TPS54880PWPR operate without an external frequency-setting resistor?
Yes - the TPS54880PWPR defaults to 350 kHz switching frequency when the RT pin (Pin 28) is left floating (open). To adjust frequency between 280 kHz and 700 kHz, connect a resistor from RT to AGND: 180 kΩ yields ~280 kHz, 100 kΩ yields ~500 kHz, and 68 kΩ yields ~700 kHz, per the oscillator frequency equations in the datasheet.
What protection features are integrated into the TPS54880PWPR?
The TPS54880PWPR integrates multiple protection mechanisms: cycle-by-cycle peak current limiting (9–12 A trip), thermal shutdown (135–165 °C with 10 °C hysteresis), under-voltage lockout (3.8 V start / 3.5 V stop), and open-drain Power Good output (active-low when VSENSE falls below 90% Vref). These eliminate need for external fault management circuitry.
