Product details
Overview
TPS6287B10HA0WRZVR from Texas Instruments is a 10A synchronous step-down DC/DC converter with I²C interface, differential remote sense, and 2.7V–6V input range. It delivers ±0.8% output voltage accuracy across 0.8V–1.55V startup range (50mV steps), features 2.6mΩ/1.5mΩ internal MOSFETs, and supports forced-PWM or power-save mode for FPGA core rail applications.
For engineers reviewing the TPS6287B10HA0WRZVR datasheet, TPS6287B10HA0WRZVR pinout, TPS6287B10HA0WRZVR application, or TPS6287B10HA0WRZVR equivalent, key selection criteria include its 1.5MHz fixed switching frequency, I²C-configurable voltage scaling, thermal warning/thermal shutdown thresholds (150°C/170°C), and WQFN-FCRLF 24-pin (3.05mm × 4.05mm) package with exposed thermal pad.
Technical Context
The TPS6287B10HA0WRZVR implements a fixed-frequency DCS-Control architecture optimized for fast transient response in high-current digital loads. Its dual-loop control integrates differential remote sensing (VOSNS/GOSNS) and I²C-programmable voltage registers to maintain tight regulation at point-of-load under dynamic current steps up to 10A.
It supports stacked operation via SYNC_OUT/MODE/SYNC daisy-chaining and offers configurable soft-start (1ms default), droop compensation, spread-spectrum clocking, and power-good monitoring with window comparator. The device operates exclusively in I²C-enabled variants-no resistor-only configuration-and uses external compensation on the COMP pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 6V - supports single-cell Li-ion, 3.3V/5V intermediate bus, and wide-input industrial supplies. |
| Output Current | 10A continuous - rated for sustained load without derating at +85°C ambient with proper PCB thermal design. |
| Output Voltage Accuracy | ±0.8% - ensures stable core voltage for 7nm/5nm FPGA/ASIC logic rails under full line/load/temperature variation. |
| Switching Frequency | 1.5MHz - enables compact 100–200nH inductor selection and reduces output ripple without compromising EMI filtering size. |
| Internal MOSFET RDS(on) | 2.6mΩ (HS) / 1.5mΩ (LS) - minimizes conduction loss and thermal rise at 10A, supporting >90% peak efficiency. |
| I²C Interface Speed | Up to 3.4MHz (High-Speed mode) - allows real-time voltage scaling during processor DVFS transitions with sub-µs latency. |
| Thermal Protection | 150°C thermal warning + 170°C shutdown - provides early fault indication and safe shutdown before silicon damage. |
Pinout & Package
TPS6287B10HA0WRZVR uses a 24-pin WQFN-FCRLF (RZV) package measuring 3.05mm × 4.05mm with an exposed thermal pad soldered to GND for optimal thermal performance (RθJA = 28°C/W on EVM).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pins 5,6,15,16) | Power input supply | Four dedicated input pins reduce trace inductance and enable parallel capacitor placement for low-impedance 2.7–6V source coupling. |
| GND (Pins 7,8,13,14) | Ground reference | Multiple ground pins minimize ground bounce and support clean return paths for high di/dt switching currents. |
| SW (Pins 9,10,11,12) | Power switch node | Four SW pins connect directly to internal high-side/low-side FETs; require tight layout to minimize ringing and EMI. |
| VSET1 / VSET2 (Pins 3,4) | Startup voltage selection | Resistor-divider inputs set initial output to 0.8V–1.55V in 50mV steps; used before I²C initialization or as fallback. |
| SDA / SCL (Pins 19,20) | I²C bidirectional interface | Supports 3.4MHz High-Speed mode; requires pull-up resistors and is disabled in stacked secondary devices. |
| MODE/SYNC (Pin 18) | Operating mode control | Pull-high for forced-PWM (best transient response); pull-low for power-save mode (highest light-load efficiency). |
| VOSNS / GOSNS (Pins 1,24) | Differential remote sense | Measures true load voltage at point-of-load; compensates for IR drop in PCB traces and connectors. |
| PG (Pin 21) | Open-drain power-good | Asserts high-impedance when VOUT is within ±4% of target; daisy-chained in stacked configurations for system-level sequencing. |
Key Features
| Feature | Design Value |
|---|---|
| Differential remote sensing | Eliminates up to 50mV of IR drop error between regulator and load, critical for sub-1V FPGA core rails. |
| I²C voltage programming | Enables dynamic VDD scaling during processor DVFS states without hardware reconfiguration or external DACs. |
| Stacked operation support | Allows two or more TPS6287B10HA0WRZVR units to share current and thermal load, enabling scalable 20A+ solutions. |
| Thermal pre-warning | Generates interrupt at 150°C junction temperature, allowing firmware to throttle load before shutdown at 170°C. |
| Programmable soft-start | Configurable ramp time (0.35–2.6ms) prevents inrush current and ensures controlled power-up of sensitive digital loads. |

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 |
|---|---|---|---|
| TPS6287B10LA0WRZVR | Same 10A rating and RZV package, but startup voltage range is 0.4V–0.775V (25mV steps) instead of 0.8V–1.55V. | Targeted for ultra-low-voltage logic rails (e.g., AI accelerator subcores), not standard FPGA core voltages. | Select TPS6287B10LA0WRZVR only if initial VOUT must be ≤0.775V; otherwise TPS6287B10HA0WRZVR matches typical 0.8V+ core requirements. |
| TPS6287B15HA0WRZVR | 15A-rated variant with identical pinout, package, and feature set-including same 0.8V–1.55V startup range and 1.5MHz frequency. | Provides headroom for future-proofing or margin-critical designs where 10A may approach thermal limits under worst-case conditions. | Choose TPS6287B15HA0WRZVR when long-term reliability at 10A under 85°C ambient demands extra current margin or derating. |
Compared with TPS6287B10LA0WRZVR, the TPS6287B10HA0WRZVR delivers higher startup voltage compatibility for mainstream FPGA cores; compared with TPS6287B15HA0WRZVR, it offers optimal cost/performance balance for verified 10A loads without over-provisioning.

FAQ
What is the default switching frequency of the TPS6287B10HA0WRZVR?
The TPS6287B10HA0WRZVR has a fixed default switching frequency of 1.5MHz. Unlike JE2 variants, it does not support selectable frequencies via FSET pin; this value is factory-set and cannot be altered by external components or I²C commands.
Does the TPS6287B10HA0WRZVR support remote sensing, and how is it implemented?
Yes, the TPS6287B10HA0WRZVR supports differential remote sensing using dedicated VOSNS and GOSNS pins. This measures voltage directly at the load to compensate for PCB trace resistance, achieving ±0.8% regulation accuracy independent of board layout losses.
Can the TPS6287B10HA0WRZVR operate in stacked configuration, and what pins are required?
Yes, the TPS6287B10HA0WRZVR supports stacked operation for current sharing. Required interconnects include SYNC_OUT → MODE/SYNC daisy-chain, shared EN and PG signals, and paralleled COMP pins. All stacked units must use identical I²C addresses and configuration registers.
What is the startup output voltage range for the TPS6287B10HA0WRZVR, and how is it selected?
The TPS6287B10HA0WRZVR supports a startup output voltage range of 0.8V to 1.55V in 50mV increments. Selection is performed via resistor dividers on VSET1 and VSET2 pins-no I²C communication is needed for initial power-on voltage establishment.
What thermal protection features does the TPS6287B10HA0WRZVR include?
The TPS6287B10HA0WRZVR includes thermal warning at 150°C (asserted via I²C register flag) and thermal shutdown at 170°C. Both thresholds have 20°C hysteresis, and the thermal warning allows host firmware to initiate throttling before catastrophic shutdown occurs.
