Product details
Overview
TPS54610MPWPREPG4 from Texas Instruments is a 3 V to 6 V input, 6 A synchronous buck PWM switcher with integrated high- and low-side MOSFETs (30 mΩ typical rDS(on)), adjustable output down to 0.9 V with ±1% reference accuracy, fixed/adjustable switching frequency (280–700 kHz), and thermal shutdown protection. It serves as a point-of-load regulator for FPGAs, DSPs, and microprocessors in high-density distributed power systems.
For engineers reviewing the TPS54610MPWPREPG4 datasheet, TPS54610MPWPREPG4 pinout, TPS54610MPWPREPG4 application, or TPS54610MPWPREPG4 equivalent, this device delivers high-efficiency DC/DC conversion in thermally enhanced 28-pin HTSSOP (PWP) PowerPAD™ packaging with integrated current limiting, power good signaling, and robust UVLO control across –55°C to 125°C operation.
Technical Context
The TPS54610MPWPREPG4 implements a voltage-mode synchronous buck architecture with an internal high-performance error amplifier (90–110 dB open-loop gain, 3–5 MHz unity-gain bandwidth), adaptive dead-time control, and leading-edge blanking (100 ns) for accurate peak-current limiting. Its integrated 30 mΩ/30 mΩ matched MOSFET pair enables >90% efficiency at 5 VIN/3.3 VOUT, 6 A load.
It supports flexible frequency configuration via RT resistor (280–700 kHz) or FSEL pin selection (350/550 kHz), synchronization up to 700 kHz, and precise regulation via 0.891 V reference (±1% over temperature). The dual-function SS/ENA pin provides enable control and programmable soft-start (2–4.5 ms internal, extendable externally).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3 V to 6 V - supports standard 3.3 V and 5 V intermediate bus rails without external LDO pre-regulation. |
| Continuous Output Current | 6 A - sustained delivery with integrated 12 A peak MOSFETs and thermal shutdown at 135–165°C. |
| Output Voltage Accuracy | ±1% at 0.9 V min - enabled by 0.891 V trimmed bandgap reference, critical for FPGA core rail tolerance. |
| Switching Frequency | 280–700 kHz adjustable - allows optimization of size (smaller inductors/caps at higher fSW) vs. efficiency. |
| rDS(on) High/Low-Side | 26–51 mΩ / 36–67 mΩ - matched MOSFETs reduce conduction loss and improve current sharing in multi-phase designs. |
| Power Good Threshold | 90% Vref with 3% hysteresis - provides clean, glitch-free reset signaling for processors and logic ICs. |
| Quiescent Current | 9.8–25 mA - low no-load consumption suitable for always-on subsystems in portable and telecom equipment. |
Pinout & Package
TPS54610MPWPREPG4 is housed in a 28-pin HTSSOP (PWP) package with exposed PowerPAD™ thermal pad (6.4 mm × 9.7 mm footprint), requiring solder connection to AGND plane for thermal performance and EMI reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AGND (Pin 1) | Analog ground reference | Return path for COMP, VSENSE, RT, FSEL, and VBIAS - must be isolated from PGND to prevent noise coupling into error amplifier. |
| VIN (Pins 20–24) | Main input supply | Connects to 3–6 V source; requires local 10 µF ceramic bypass to PGND pins to minimize high-frequency ripple injection. |
| PH (Pins 6–14) | Phase node | Switching node between internal MOSFETs; connects directly to output inductor - layout minimization critical for EMI and efficiency. |
| BOOT (Pin 5) | Bootstrap driver supply | Requires 0.022–0.1 µF low-ESR capacitor to PH to generate gate drive voltage for high-side FET. |
| VSENSE (Pin 2) | Error amplifier inverting input | Monitors output via resistor divider; sets regulated voltage with 0.891 V reference - determines output accuracy and loop stability. |
| COMP (Pin 3) | Error amplifier output | Drives external Type II/III compensation network; open-loop gain and bandwidth define transient response and phase margin. |
| PWRGD (Pin 4) | Open-drain power-good signal | Asserts high when VSENSE ≥ 90% Vref; used for processor reset, sequencing, or fault indication - sinks 2.5 mA max. |
| SS/ENA (Pin 26) | Enable & slow-start control | Logic-enable threshold 0.82–1.4 V; internal 3.35 ms soft-start prevents inrush - external capacitor extends ramp time linearly. |
| FSEL (Pin 27) | Frequency select/sync input | Low = 350 kHz, high = 550 kHz; also accepts external sync signal (330–700 kHz) when RT resistor is configured. |
| RT (Pin 28) | Frequency set resistor | Resistor to AGND sets fSW: 180 kΩ → 280 kHz, 68 kΩ → 700 kHz - enables precise EMI compliance tuning. |
| PGND (Pins 15–19) | Power ground return | High-current return for low-side FET and input/output capacitors - must connect to large copper area and tie to AGND at single point. |
| VBIAS (Pin 25) | Bias regulator output | 2.7–2.95 V internal LDO output; powers internal circuitry and may serve as stable reference for external analog circuits. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 30 mΩ MOSFETs | Eliminates external discrete switches and gate drivers, reducing BOM count and PCB area by >30% versus controller-based solutions. |
| Adjustable 280–700 kHz switching | Enables compact magnetics design while maintaining >85% efficiency at full 6 A load across input range. |
| Thermal shutdown with 10°C hysteresis | Prevents latch-up during overload or poor heatsinking; automatic recovery after cooling ensures system resilience. |
| 0.891 V ±1% reference voltage | Supports tight-tolerance core rails for modern FPGAs (e.g., Xilinx Kintex-7, Intel Cyclone V) without external trimming. |
| PowerPAD™ thermal package | Reduces junction-to-ambient thermal resistance to 18.2°C/W (with solder), enabling 6 A operation without external heatsink. |
| Programmable soft-start (2–4.5 ms) | Controls inrush current during power-up, preventing input rail collapse and avoiding false PWRGD assertion. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS54616MPWPREP | Fixed 3.3 V output (non-adjustable); identical package, pinout, and thermal specs. | Eliminates external feedback resistors but lacks flexibility for custom output voltages. | Select when 3.3 V is required and board space for R-divider must be minimized. |
| LM2678SDX-ADJ/NOPB | 5 A rating, 8–40 V input, external MOSFETs; larger SO-8 package, no PowerPAD™. | Higher input range suits industrial 24 V systems but requires external FETs and gate drivers. | Choose only for legacy 24 V input designs where TPS54610MPWPREPG4's 3–6 V range is insufficient. |
Compared with TPS54610MPWPREPG4, TPS54616MPWPREP offers plug-and-play 3.3 V regulation but sacrifices adjustability, while LM2678SDX-ADJ/NOPB supports wider input voltage at the cost of higher component count, larger footprint, and reduced thermal efficiency.

FAQ
What is the maximum continuous output current of the TPS54610MPWPREPG4?
The TPS54610MPWPREPG4 delivers 6 A continuous output current with integrated MOSFETs. Its 12 A peak current limit and thermal shutdown (trip at 135–165°C) protect against overload. Derating is required above 85°C ambient per the dissipation ratings table - at 125°C junction, maximum safe output drops to ~4.2 A with proper PowerPAD™ soldering and thermal vias.
Does the TPS54610MPWPREPG4 require external MOSFETs?
No, the TPS54610MPWPREPG4 integrates both high-side and low-side power MOSFETs (30 mΩ typical rDS(on)) on-die. This eliminates the need for external switches, gate drivers, or bootstrap diodes - simplifying design, reducing board area, and improving efficiency compared to controller-only solutions like the TPS40055M.
Can the TPS54610MPWPREPG4 operate from a 3.3 V input rail?
Yes, the TPS54610MPWPREPG4 supports 3 V to 6 V input, making it fully compatible with 3.3 V intermediate distribution buses. At 3.3 VIN, its minimum controllable on-time (200 ns) and 90% maximum duty cycle allow regulation down to 0.9 VOUT - verified in TI's application note SLVA107 for high-frequency, low-input designs.
How is output voltage adjusted on the TPS54610MPWPREPG4?
Output voltage is set via an external resistor divider from VOUT to AGND, connected to the VSENSE pin. With a 0.891 V internal reference, VO = 0.891 × (1 + R1/R2). For example, 1.2 V output uses R1 = 3.74 kΩ and R2 = 10 kΩ. Compensation components (R/C network from COMP to VSENSE) must be selected per TI's SWIFT™ designer tool or application note SLLA183.
What thermal management is required for full 6 A operation of the TPS54610MPWPREPG4?
Full 6 A operation requires soldering the PowerPAD™ to a ≥3″×3″ 1-oz copper analog ground plane with ≥12 thermal vias (8×0.013″ in pad, 4×0.018″ under package). Without this, power dissipation is limited to 2.2 W at 85°C ambient. TI's recommended land pattern (SLMA002) and layout guidelines in SLLA183 must be followed to maintain TJ ≤ 125°C.
