Product details
Overview
TPS54010MPWPREP from Texas Instruments is a radiation-hardened, synchronous buck PWM converter 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 compensated control loop for point-of-load regulation in high-performance FPGAs and DSPs.
For engineers reviewing the TPS54010MPWPREP datasheet, TPS54010MPWPREP pinout, TPS54010MPWPREP application, or TPS54010MPWPREP equivalent, key selection criteria include its –55°C to 125°C military-grade operating temperature, 28-pin HTSSOP PowerPAD™ package with thermal pad, 280–700 kHz adjustable switching frequency, 0.891-V internal reference accuracy (±1%), and integrated peak-current-limit protection with thermal shutdown.
Technical Context
The TPS54010MPWPREP implements a voltage-mode PWM control architecture with an externally compensated error amplifier, enabling flexible L-C filter design and fast transient response under load steps. Its dual-power-rail structure separates PVIN (2.2–4 V) for power MOSFETs and VIN (3–4 V) for control circuitry, supporting efficient operation in low-voltage, high-density systems.
It features a true high-performance voltage error amplifier (90–110 dB open-loop gain, 3–5 MHz unity-gain bandwidth), programmable soft-start via SS/ENA pin (2.1–4.1 ms internal timing), and synchronization capability via SYNC pin (300–700 kHz external clock acceptance). The device integrates undervoltage lockout (UVLO start at 2.95 V, 0.11-V hysteresis) and power-good signaling with 93% VREF threshold.

Pinout & Package
The TPS54010MPWPREP is housed in a thermally enhanced 28-pin Plastic HTSSOP (PWP) package with exposed PowerPAD™ for direct PCB thermal coupling. The PowerPAD must be soldered to a dedicated AGND plane using ≥12 thermal vias (8 in pad area, 4 under package) per TI layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AGND (Pin 1) | Analog ground reference | Return path for compensation network, VSENSE divider, SS/ENA capacitor, VBIAS capacitor, and RT resistor - must be isolated from PGND except at single-point connection |
| VSENSE (Pin 2) | Error amplifier inverting input | Connects to output voltage divider - senses regulated output and compares against 0.891-V internal reference |
| COMP (Pin 3) | Error amplifier output | Drives external Type-III compensation network (R/C) between COMP and VSENSE - determines loop stability and transient response |
| PWRGD (Pin 4) | Power-good open-drain output | Asserts high when VSENSE > 93% VREF; used for processor reset sequencing and fault monitoring |
| BOOT (Pin 5) | Bootstrap gate drive supply | Supplies floating voltage to high-side FET driver via 0.022–0.1-µF ceramic capacitor to PH - critical for proper high-side switching |
| PH (Pins 6–14) | Phase node | Junction of internal high- and low-side MOSFETs - connects directly to output inductor - high di/dt node requiring minimized trace area |
| PGND (Pins 15–19) | Power ground return | High-current return for low-side FET and input/output capacitors - must be tied to large copper pour and connected to AGND at single point |
| PVIN (Pins 20–23) | Power MOSFET supply | Input rail for internal FETs and bias regulator - bypassed with ≥10-µF X5R/X7R ceramic capacitor close to pins |
| VIN (Pin 24) | Control circuit supply | Input for internal logic, PWM comparator, and error amplifier - bypassed with ≥1-µF ceramic capacitor |
| VBIAS (Pin 25) | Bias regulator output | Internally regulated ~2.8-V supply for gate drivers - bypassed with 0.1–1.0-µF ceramic capacitor to AGND |
| SS/ENA (Pin 26) | Enable & soft-start control | Logic-enable input (0.82–1.4 V threshold); also accepts external capacitor to set 2.1–4.1 ms startup ramp - prevents inrush current |
| SYNC (Pin 27) | Frequency synchronization | Accepts external clock (300–700 kHz) or selects internal 350/550 kHz modes - enables system-level clock alignment |
| RT (Pin 28) | Frequency setting input | Connects to AGND via precision resistor (e.g., 68 kΩ for 700 kHz) - sets free-running oscillator frequency with ±10% tolerance |

Applications
| High-Performance FPGA Core Supply | ASIC Point-of-Load Regulation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS54020MPWPREP | Higher 20-A output rating, same 2.2–4-V input, identical PWP package and pinout, but 12-mΩ FETs and higher quiescent current (13 mA vs 10 mA) | Better suited for future-proofing or margin-critical 16–18-A loads; less efficient at light loads due to higher IQ | Select TPS54020MPWPREP only if >14-A headroom or higher peak current capability is required; otherwise TPS54010MPWPREP offers optimal balance of size, efficiency, and cost |
| LMZ12012TZE/NOPB | Integrated inductor module (12-A max), fixed 3.3-V/5-V/12-V outputs or adjustable 0.8–6-V, larger 16-pin QFN package, no external compensation | Simpler layout and faster time-to-market for non-critical applications; lacks TPS54010MPWPREP's fine output adjustability and military temp range | Choose LMZ12012TZE/NOPB for rapid prototyping or space-constrained boards where 12-A limit and commercial temp range (–40°C to +125°C) are acceptable |
Compared with TPS54010MPWPREP, TPS54020MPWPREP provides higher current headroom at the expense of slightly lower light-load efficiency, while LMZ12012TZE/NOPB trades design flexibility and military qualification for integration simplicity and reduced BOM count.

FAQ
What is the maximum continuous output current supported by the TPS54010MPWPREP?
The TPS54010MPWPREP supports 14-A continuous output current under recommended operating conditions (PVIN = 2.2–4 V, TJ ≤ 125°C, proper PCB thermal design). This rating is validated with the 28-pin HTSSOP PowerPAD™ package and requires adherence to TI's layout guidelines-including minimum 12 thermal vias and ≥3″×3″ 1-oz copper area-to maintain junction temperature within limits.
Does the TPS54010MPWPREP require external compensation components?
Yes, the TPS54010MPWPREP is externally compensated: a Type-III compensation network (typically R1, R3, R5, C6, C7, C8) must be connected between COMP and VSENSE pins. This design choice enables precise loop tuning for diverse output filter configurations (e.g., ceramic, polymer, or hybrid capacitors) and ensures stability across the full 0.9–4-V output range and 280–700 kHz frequency band.
What is the purpose of the separate PVIN and VIN supply pins on the TPS54010MPWPREP?
The TPS54010MPWPREP uses separate PVIN (2.2–4 V) and VIN (3–4 V) rails to isolate high-current power switching from low-noise control circuitry. PVIN powers the integrated 8-mΩ MOSFETs and bias regulator, while VIN supplies the PWM comparator, error amplifier, and logic-reducing cross-coupling noise and enabling independent optimization of each rail's bypassing and routing.
Can the TPS54010MPWPREP operate over the full military temperature range without derating?
Yes, the TPS54010MPWPREP is fully specified and tested from –55°C to +125°C junction temperature per V62/13604-01XE qualification. All key parameters-including 0.891-V reference accuracy (±1%), 8-mΩ RDS(on), current limit (14.5–21 A), and thermal shutdown (135–165°C)-are guaranteed across this range, with no current or power derating required when PCB thermal design meets TI's PowerPAD™ layout recommendations.
How is the switching frequency programmed on the TPS54010MPWPREP?
The TPS54010MPWPREP switching frequency is programmed via the RT pin: connect a precision resistor from RT to AGND to set frequencies from 280 kHz (180 kΩ) to 700 kHz (68 kΩ). Alternatively, the SYNC pin can select internal 350-kHz (SYNC ≤ 0.8 V) or 550-kHz (SYNC ≥ 2.5 V) modes. External synchronization accepts 300–700 kHz clocks, enabling system-level EMI reduction through clock alignment.
