Product details
Overview
TPS6287B10VA0WRZVR 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 0.4V–1.675V, features 2.6mΩ/1.5mΩ internal MOSFETs, and supports forced-PWM or power-save mode for FPGA, ASIC, and optical network core supplies.
For engineers reviewing the TPS6287B10VA0WRZVR datasheet, TPS6287B10VA0WRZVR pinout, TPS6287B10VA0WRZVR application, or TPS6287B10VA0WRZVR equivalent, key selection criteria include its 10A rated current, WQFN-FCRLF (RZV) 24-pin 3.05mm × 4.05mm package, I²C-compatible 3.4MHz interface, differential remote sensing capability, and resistor-selectable startup voltage (0.4V–1.675V in 5mV steps).
Technical Context
The TPS6287B10VA0WRZVR implements a fixed-frequency DCS-Control architecture optimized for fast transient response in high-current digital loads. Its dual-MOSFET power stage (2.6mΩ HS / 1.5mΩ LS) enables high efficiency at 10A while maintaining thermal stability up to 125°C junction temperature.
Differential remote sensing (VOSNS/GOSNS) compensates for PCB IR drop, ensuring ±0.8% DC output accuracy at the point-of-load. Startup voltage is set via VSET1/VSET2 pins using external resistors - supporting three ranges: 0.4V–0.71875V (1.25mV), 0.4V–1.0375V (2.5mV), or 0.4V–1.675V (5mV) resolution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 6V - supports single-cell Li-ion, 3.3V/5V rails, and intermediate bus architectures. |
| Output Current Rating | 10A continuous - sufficient for mid-tier FPGA core domains and ASIC subsystems. |
| Output Voltage Accuracy | ±0.8% - ensures stable logic supply under full load and temperature variation. |
| Internal MOSFET RDS(on) | 2.6mΩ (HS) / 1.5mΩ (LS) - minimizes conduction loss and thermal rise at 10A. |
| I²C Interface Speed | Up to 3.4MHz - enables rapid dynamic voltage scaling (DVS) for performance-state transitions. |
| Switching Frequency | 1.5MHz (default) - balances size of external inductor/capacitor with EMI and efficiency. |
| Remote Sense Accuracy | Differential VOSNS/GOSNS - eliminates PCB trace resistance error, critical for <1V core supplies. |
Pinout & Package
TPS6287B10VA0WRZVR uses the RZV package: 24-pin WQFN-FCRLF, 3.05mm × 4.05mm body with exposed thermal pad soldered to GND for optimal thermal performance (RθJB = 6.5°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOSNS | Differential output voltage sense (+) | Connects directly to load VDD for precise point-of-load regulation. |
| GOSNS | Differential output ground sense (–) | Connects to load ground return path to cancel PCB IR drop error. |
| VSET1 / VSET2 | Startup output voltage select inputs | Resistor-divider or direct tie to GND/VIN sets initial VOUT (0.4V–1.675V range). |
| EN | Enable control input | Active-high logic; requires ≥15kΩ series resistor; enables sequencing and fault isolation. |
| MODE/SYNC | Operating mode select / sync input | Pull low for power-save mode; pull high for forced-PWM; accepts external clock for synchronization. |
| PG | Open-drain power-good output | Signals valid output after soft-start; window comparator ensures ±4% tolerance on VOUT. |
| COMP | Loop compensation node | External RC network sets loop bandwidth and phase margin for stability across load transients. |
| SW | Power switch node | Connects to external inductor; high di/dt node requiring tight layout and Kelvin routing. |
| VIN (Pins 5,6,15,16) | Input power supply | Four dedicated VIN pins reduce impedance and improve current sharing into internal FETs. |
| GND (Pins 7,8,13,14,22) | Ground reference | Multiple GND pins minimize ground bounce and support separate analog/digital return paths. |
Key Features
| Feature | Design Value |
|---|---|
| Differential remote sensing | Compensates for up to 100mV PCB voltage drop between regulator and load, preserving ±0.8% accuracy at point-of-load. |
| Adjustable soft-start time | Configurable ramp times (0.35–2.6ms) prevent inrush current and ensure controlled power-up sequencing. |
| I²C programmable output voltage | Enables real-time dynamic voltage scaling (DVS) without hardware changes - critical for adaptive computing workloads. |
| Thermal pre-warning & shutdown | Triggers warning at 150°C and shuts down at 170°C with 20°C hysteresis - protects silicon and system reliability. |
| Output discharge function | Activates internal 2.7–9.2Ω discharge path when disabled - prevents floating outputs and ensures safe power-down states. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS6287B10LA0WRZVR | Includes I²C interface; startup voltage range limited to 0.4V–0.775V (25mV steps); same 10A rating and RZV package. | Preferred where dynamic voltage scaling and telemetry monitoring are required; not suitable for 0.8V+ startup voltages. | Select when I²C-based system-level power management is mandatory and startup voltage ≤0.775V. |
| TPS6287B10HA0WRZVR | Includes I²C interface; startup voltage range 0.8V–1.55V (50mV steps); identical electrical specs otherwise. | Targeted at higher-VOUT applications like DDR I/O or auxiliary rails; lacks low-voltage startup flexibility. | Choose when startup voltage must be ≥0.8V and I²C telemetry is needed - e.g., memory subsystems. |
Compared with TPS6287B10LA0WRZVR and TPS6287B10HA0WRZVR, the TPS6287B10VA0WRZVR offers the broadest startup voltage range (0.4V–1.675V) without I²C, making it optimal for cost-sensitive, fixed-VOUT designs where remote sense and precision regulation are critical but digital control is unnecessary.

FAQ
What is the maximum output voltage supported by the TPS6287B10VA0WRZVR?
The TPS6287B10VA0WRZVR supports an output voltage range of 0.4V to 1.675V, or up to (VIN – 1.5V), whichever is lower. Its three selectable resolution modes - 1.25mV, 2.5mV, and 5mV steps - allow precise tuning across this full span. This range covers most modern FPGA, ASIC, and AI accelerator core supply requirements, including sub-1V logic rails.
Does the TPS6287B10VA0WRZVR support remote sensing, and how is it implemented?
Yes, the TPS6287B10VA0WRZVR implements differential remote sensing using dedicated VOSNS (output voltage sense) and GOSNS (output ground sense) pins. This configuration measures voltage directly at the load, rejecting PCB trace resistance errors up to ±100mV. The design ensures ±0.8% DC output accuracy at the point-of-load - critical for <1V digital supplies where even 20mV drop causes functional failure.
What package type and thermal characteristics does the TPS6287B10VA0WRZVR use?
The TPS6287B10VA0WRZVR uses the RZV package: a 24-pin WQFN-FCRLF measuring 3.05mm × 4.05mm with an exposed thermal pad. Its thermal metrics include RθJB = 6.5°C/W (junction-to-board) and RθJA = 28°C/W (JEDEC standard), enabling reliable 10A operation at up to 125°C junction temperature when properly mounted on a 2-layer PCB with thermal vias.
Can the TPS6287B10VA0WRZVR be used in stacked configurations for higher current?
No - the TPS6287B10VA0WRZVR variant lacks the SYNC_OUT and MODE/SYNC synchronization logic required for stacked operation. Only JE2 and LA/HA variants (e.g., TPS6287B10JE2WRZVR) support stacking. The VA suffix indicates a non-synchronizable, standalone configuration optimized for simplicity and cost in fixed-output applications.
What are the key differences between TPS6287B10VA0WRZVR and TPS6287B10LA0WRZVR?
The TPS6287B10VA0WRZVR omits the I²C interface and supports the widest startup voltage range (0.4V–1.675V), while the TPS6287B10LA0WRZVR includes full I²C functionality but limits startup to 0.4V–0.775V. Both share identical 10A rating, RZV package, MOSFET specs, and remote sensing - making the VA variant ideal for fixed-VOUT systems where digital control adds no value.
