Texas Instruments TPS54010MPWPEP

Overview

TPS54010MPWPEP from Texas Instruments is a radiation-hardened, synchronous buck PWM switcher with integrated 8-mΩ high- and low-side MOSFETs, delivering up to 14-A continuous output current from a 2.2-V to 4-V input range, adjustable down to 0.9-V output voltage, and externally programmable switching frequency from 280 kHz to 700 kHz. It serves as a point-of-load regulator for high-performance FPGAs and DSPs in defense and aerospace systems.

For engineers reviewing the TPS54010MPWPEP datasheet, TPS54010MPWPEP pinout, TPS54010MPWPEP application, or TPS54010MPWPEP equivalent, this page delivers verified electrical specs, thermal metrics, PowerPAD™ package layout guidance, and military-grade reliability data for embedded power design under –55°C to 125°C operating conditions.

Technical Context

The TPS54010MPWPEP implements a voltage-mode PWM control architecture with an internally compensated error amplifier (90–110 dB open-loop gain, 3–5 MHz unity-gain bandwidth), adaptive dead-time logic, and peak-current-limit protection. Its dual-input architecture separates PVIN (2.2–4 V) for power FETs and VIN (3–4 V) for control circuitry, enabling efficient operation on distributed 2.5-V/3.3-V power buses.

Thermal management relies on the exposed PowerPAD™ in the 28-pin HTSSOP (PWP) package, achieving θJCbot = 0.9°C/W and θJB = 11.6°C/W. The device integrates undervoltage lockout (UVLO start at 2.95 V), internal slow-start (3.35 ms typical), and open-drain PWRGD with 93% Vref threshold and 3% hysteresis for precise supply sequencing.

Key Specifications

Pinout & Package

The TPS54010MPWPEP is housed in a thermally enhanced 28-pin HTSSOP (PWP) package with an exposed PowerPAD™ for direct PCB thermal coupling. The PowerPAD must be soldered to a dedicated AGND plane using ≥12 thermal vias (8×0.013″ under pad, 4×0.018″ under body) per TI layout guidelines.

Equivalent & Alternatives

The following parts are listed as comparable options for similar synchronous buck regulator applications.

Compared with TPS54020MPWPEP, the TPS54010MPWPEP offers tighter thermal resistance (0.9°C/W vs 1.2°C/W) and lower quiescent current (6–10 mA vs 12–15 mA), making it preferable for thermally constrained 14-A applications; versus LMZ12012TZE/NOPB, it provides full adjustability, higher current, and superior efficiency at the cost of external component design effort.

FAQ

What is the maximum continuous output current of the TPS54010MPWPEP?

The TPS54010MPWPEP delivers 14-A continuous output current under recommended operating conditions (PVIN = 2.2 V to 4 V, TJ ≤ 125°C, proper PCB thermal design). This rating assumes use of the exposed PowerPAD™ with ≥12 thermal vias and adequate copper area per TI's SLVSBN3 layout guidelines. Derating applies above 125°C junction temperature.

Does the TPS54010MPWPEP require external compensation components?

Yes, the TPS54010MPWPEP is externally compensated: the COMP pin must be connected to VSENSE via a Type-II or Type-III network (typically R-C-R-C configuration) to stabilize the control loop. TI's SWIFT Designer software and Application Note SLVA432 provide validated component values based on selected LOUT, COUT, and target crossover frequency.

What is the purpose of the separate PVIN and VIN pins on the TPS54010MPWPEP?

PVIN supplies power to the integrated high- and low-side MOSFETs and internal bias regulator (VBIAS), while VIN powers only the control circuitry (PWM, error amp, logic). This separation allows system designers to source PVIN from a low-noise 2.5-V or 3.3-V distributed power bus and VIN from a cleaner 3.3-V rail, improving overall efficiency and noise immunity.

Can the TPS54010MPWPEP be synchronized to an external clock?

Yes, the TPS54010MPWPEP supports external synchronization via the SYNC pin. When driven with a TTL/CMOS-compatible square wave (0.8 V low, 2.5 V high), it locks to frequencies between 300 kHz and 700 kHz. The RT pin must be connected to AGND with a resistor to set the internal oscillator's free-run frequency as a fallback if SYNC is inactive.

What thermal performance can be expected from the TPS54010MPWPEP in a standard PCB layout?

With the recommended layout - including a 5-mm² exposed PowerPAD™ soldered to AGND with 12 thermal vias and a 3″ × 3″ 1-oz copper plane - the TPS54010MPWPEP achieves θJB = 11.6°C/W and θJCbot = 0.9°C/W. At 14-A load and 1.5-V output, typical power dissipation is ~2.5 W, resulting in <30°C temperature rise above ambient under still-air conditions.
