Product details
Overview
TPS6287B25LA0WRZVR from Texas Instruments is a 25A synchronous step-down DC/DC converter with I²C interface, differential remote sense, and fast transient response. It operates from 2.7V to 6V input, delivers output voltage from 0.4V to 1.675V with ±0.8% DC accuracy, and integrates 2.6mΩ/1.5mΩ power MOSFETs for high-efficiency core regulation in FPGA and ASIC power delivery.
For engineers reviewing the TPS6287B25LA0WRZVR datasheet, TPS6287B25LA0WRZVR pinout, TPS6287B25LA0WRZVR application, or TPS6287B25LA0WRZVR equivalent, key selection criteria include its 25A rated current, I²C programmability (up to 3.4MHz), selectable switching frequencies (1.5MHz default), forced-PWM/power-save mode control, and differential remote sensing for point-of-load accuracy.
Technical Context
The TPS6287B25LA0WRZVR implements a fixed-frequency DCS-Control architecture optimized for sub-1µs load transient response in high-performance digital loads. Its dual-loop control supports both voltage-mode regulation via COMP pin compensation and droop-based current sharing in stacked configurations.
It features integrated thermal pre-warning (150°C) and shutdown (170°C), output discharge (2.7–9.2Ω), and a dedicated I²C interface supporting real-time VOUT monitoring, temperature warnings, and dynamic voltage scaling - all while maintaining ±0.8% output accuracy across temperature and line/load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 25A continuous - enables single-chip core supply for mid-tier FPGAs without external current sharing circuitry. |
| Input Voltage Range | 2.7V to 6V - compatible with 3.3V, 5V, and intermediate bus architectures in telecom and storage systems. |
| Output Voltage Accuracy | ±0.8% - ensures stable logic rail compliance under full temperature (-40°C to +125°C) and load range. |
| Switching Frequency | 1.5MHz (default) - balances efficiency, size, and EMI; supports synchronization and stacking via SYNC_OUT/MODE pins. |
| I²C Interface Speed | Up to 3.4MHz (high-speed mode) - enables rapid voltage updates (<100µs register write) for DVFS in processor cores. |
| Power MOSFET RDS(on) | 2.6mΩ (HS) / 1.5mΩ (LS) - minimizes conduction loss at 25A, enabling >92% peak efficiency at 1V/25A with 5V input. |
| Differential Remote Sense | VOSNS/GOSNS inputs - compensates for PCB IR drop up to ±100mV, maintaining regulation accuracy at point-of-load. |
Pinout & Package
RZV package: 24-pin WQFN-FCRLF (3.05mm × 4.05mm), thermally enhanced with exposed pad soldered to GND for low RθJA (28°C/W on EVM).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pins 5,6,15,16) | Power input | Four parallel input paths reduce trace inductance and improve high-current stability; requires local 10–22µF ceramic per pin. |
| SW (Pins 9,10,11,12) | Power switch node | Four paralleled SW outputs drive external inductor; layout must minimize loop area to suppress EMI and ringing. |
| VOSNS / GOSNS | Differential output sense | High-impedance feedback pair enables precise point-of-load regulation; routing must be matched and away from noise sources. |
| SDA / SCL (Pins 19,20) | I²C bidirectional interface | Supports up to 3.4MHz operation; requires pull-up resistors (1.2–5V compatible) and isolation from switching nodes. |
| EN (Pin 2) | Enable control | Logic-level input with internal 1.4–3kΩ pulldown during stacked start-up; series resistor ≥15kΩ required for direct VIN tie. |
| MODE/SYNC (Pin 18) | Operating mode select | Pull-low = power-save mode (efficiency-optimized); pull-high = forced-PWM (low ripple, best transient response). |
Key Features
| Feature | Design Value |
|---|---|
| Stackable architecture | Up to three TPS6287B25LA0WRZVR devices can be daisy-chained via SYNC_OUT → MODE/SYNC to deliver 75A with automatic current balancing. |
| Programmable soft-start | Four ramp times (0.35–2.6ms) selectable via CONTROL2[1:0] register - prevents inrush current in multi-rail systems. |
| Droop compensation | Enables accurate current-sharing in stacked mode; ±3mV accuracy for TPS6287B25 ensures <±2% current mismatch at 25A per device. |
| Thermal warning & shutdown | Dedicated TW (150°C) and TSD (170°C) thresholds with 20°C hysteresis - provides early system throttling before catastrophic failure. |
| Output discharge | Integrated 2.7–9.2Ω discharge path - safely discharges output capacitance during shutdown, meeting sequencing requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS6287B25JE2WRZVR | Includes FSET pin for 1.5/2.25/2.5/3MHz frequency selection; different VSEL/I²C address mapping. | Targeted for Jacinto platform integration; supports non-synchronous mode and SSC by default. | Select when flexible frequency tuning or Jacinto-specific startup configuration is required. |
| ISL9123IRAJZ-T7A | 15A rated, 2.5V–5.5V input, no I²C, uses analog VSET pins only; smaller 2.5mm × 3mm package. | Limited to lower-current applications; lacks remote sense, stacking, and telemetry capabilities. | Choose for cost-sensitive, space-constrained designs where 25A and digital control are unnecessary. |
Compared with TPS6287B25JE2WRZVR, the TPS6287B25LA0WRZVR offers simpler frequency configuration (fixed 1.5MHz) and broader startup voltage selection (0.4–0.775V/0.8–1.55V ranges), while ISL9123IRAJZ-T7A trades programmability and current capability for footprint reduction and analog simplicity.

FAQ
What is the maximum output current rating of the TPS6287B25LA0WRZVR?
The TPS6287B25LA0WRZVR is rated for 25A continuous output current under recommended operating conditions (TJ ≤ 125°C, proper thermal design). Its internal 2.6mΩ/1.5mΩ MOSFETs and 3.05mm × 4.05mm RZV package enable this rating without external current sharing. Derating applies above 85°C ambient or with inadequate PCB copper.
Does the TPS6287B25LA0WRZVR support remote voltage sensing?
Yes, the TPS6287B25LA0WRZVR supports true differential remote sensing via dedicated VOSNS and GOSNS pins. This feature compensates for PCB trace resistance up to ±100mV, ensuring ±0.8% output voltage accuracy precisely at the load - critical for low-voltage, high-current FPGA and ASIC core rails.
Can multiple TPS6287B25LA0WRZVR devices be operated in parallel?
Yes, the TPS6287B25LA0WRZVR supports optional stacked operation using SYNC_OUT and MODE/SYNC pins. Up to three devices can be daisy-chained to deliver up to 75A with automatic current balancing via droop compensation, eliminating need for external phase controllers or complex timing alignment.
What I²C speeds does the TPS6287B25LA0WRZVR support?
The TPS6287B25LA0WRZVR supports I²C standard mode (100kHz), fast mode (400kHz), fast mode plus (1MHz), and high-speed mode up to 3.4MHz (with ≤100pF bus capacitance). Its I²C interface enables real-time voltage adjustment, temperature monitoring, and power-good status reporting without interrupting regulation.
What is the default switching frequency of the TPS6287B25LA0WRZVR?
The TPS6287B25LA0WRZVR defaults to 1.5MHz switching frequency in PWM operation. Unlike JE2 variants, it lacks an FSET pin; frequency selection is fixed unless externally synchronized via the MODE/SYNC pin. This simplifies design for applications prioritizing EMI predictability over tunability.
