Product details
Overview
TPS6287B15VA0WRZVR from Texas Instruments is a 15A synchronous step-down DC/DC converter with I²C interface, differential remote sense, and fast transient response. It operates from 2.7V–6V input, delivers 0.4V–1.675V output 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 TPS6287B15VA0WRZVR datasheet, TPS6287B15VA0WRZVR pinout, TPS6287B15VA0WRZVR application, or TPS6287B15VA0WRZVR equivalent, key selection factors include its resistor- or I²C-programmable startup voltage (0.4V–1.675V), forced-PWM/power-save mode control, thermal pre-warning capability, and stacked operation support for current scaling.
Technical Context
The TPS6287B15VA0WRZVR implements a fixed-frequency DCS-Control™ architecture optimized for sub-1µs load transient response in high-performance digital loads. Its dual-loop compensation supports external tuning via the COMP pin, while differential VOSNS/GOSNS sensing enables precise point-of-load regulation under dynamic current steps.
It features an I²C-compatible interface operating up to 3.4MHz (high-speed mode), supporting real-time voltage monitoring, thermal warnings, and programmable soft-start timing. Unlike JE2 variants, this VA0 version uses VSET1/VSET2 pins-not FSET-for startup voltage selection and lacks frequency-select capability.

Pinout & Package
TPS6287B15VA0WRZVR is housed in a thermally enhanced 24-pin WQFN-FCRLF (RZV) package measuring 3.05mm × 4.05mm with exposed thermal pad soldered to GND for optimal heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pins 5,6,15,16) | Power input supply | Four dedicated input pins reduce trace inductance and enable robust decoupling near high di/dt switching node. |
| SW (Pins 9,10,11,12) | Switch node | Four paralleled SW outputs distribute current and minimize parasitic inductance for clean gate drive and EMI control. |
| VOSNS / GOSNS | Differential output voltage sense | Enables accurate remote sensing at load point-critical for <1% regulation error across PCB voltage drops. |
| VSET1 / VSET2 | Startup voltage selection inputs | Resistor-divider or direct tie to GND/VIN sets initial output voltage before I²C configuration; no FSET pin present. |
| EN | Enable control | Active-high logic input with internal 1.4–3kΩ pulldown during stacked operation-supports synchronized multi-rail sequencing. |
| SDA / SCL | I²C bidirectional interface | Supports addressable communication (default 0x44–0x47) for telemetry, margining, and dynamic voltage scaling. |
| PG | Open-drain power-good | Window comparator output asserts after soft-start completes and VOUT remains within ±4% of target for >40µs. |
| COMP | Loop compensation node | External RC network connects here to tailor bandwidth and phase margin for specific output capacitor ESR/ESL. |
Key Features
| Feature | Design Value |
|---|---|
| Differential remote sensing | Compensates for IR drop across PCB traces-maintains ±0.8% regulation at point-of-load even with 50mΩ path resistance. |
| Stacked operation support | SYNC_OUT/MODE-SYNC daisy-chaining allows up to 3 devices to share load and spread thermal dissipation across board area. |
| Programmable soft-start | Four ramp time options (0.35ms–2.6ms) via CONTROL2 register-prevents inrush current and avoids undershoot on hot-plug events. |
| Thermal pre-warning | Digital alert at 150°C junction temperature gives host processor time to throttle clocks or shed load before shutdown at 170°C. |
| Output discharge | Internal 2.7–9.2Ω discharge FET actively pulls VOUT to GND when disabled-ensures safe power-down in systems with hold-up capacitors. |

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 |
|---|---|---|---|
| TPS6287B15JE2WRZVR | Includes FSET pin for 1.5/2.25/2.5/3MHz frequency selection; different I²C address mapping (0x44–0x47 via VSET). | Required for Jacinto platform integration and designs needing higher switching frequencies to shrink magnetics. | Select JE2 if frequency flexibility or TI Jacinto compatibility is needed; VA0 is preferred for fixed 1.5MHz operation with simpler startup setup. |
| MP2965AGU-Z | 15A monolithic buck with PMBus interface, 3.3V–16V input, no remote sense, ±1.0% output accuracy. | Suitable for industrial 12V intermediate bus systems but lacks differential sensing for precision point-of-load regulation. | Choose MP2965AGU-Z for wider input range and PMBus ecosystem compatibility; TPS6287B15VA0WRZVR excels in low-input, high-accuracy FPGA/ASIC use cases. |
Compared with TPS6287B15JE2WRZVR, the TPS6287B15VA0WRZVR offers simplified startup via VSET1/VSET2 only and fixed 1.5MHz operation-reducing layout complexity and component count. Versus MP2965AGU-Z, it delivers tighter DC accuracy and integrated remote sensing critical for sub-1V digital rails.

FAQ
What is the default switching frequency of the TPS6287B15VA0WRZVR?
The TPS6287B15VA0WRZVR has a fixed default switching frequency of 1.5MHz. Unlike JE2 variants, it does not include an FSET pin and cannot be configured for 2.25MHz, 2.5MHz, or 3MHz operation-making it optimized for balanced efficiency, size, and EMI performance in standard 12V or 5V intermediate bus designs.
Does the TPS6287B15VA0WRZVR support remote sensing, and how is it implemented?
Yes, the TPS6287B15VA0WRZVR supports true differential remote sensing using dedicated VOSNS and GOSNS pins. This allows the device to monitor output voltage directly at the load, compensating for PCB trace resistance and ensuring ±0.8% regulation accuracy at the point-of-load-even with up to 50mΩ of path impedance.
How is the startup output voltage set on the TPS6287B15VA0WRZVR?
The TPS6287B15VA0WRZVR uses resistor dividers on VSET1 and VSET2 pins to select startup voltage from 0.4V to 1.675V in 5mV steps. No external EEPROM or I²C initialization is required for basic operation-enabling reliable power-on behavior independent of host firmware readiness.
Can multiple TPS6287B15VA0WRZVR devices be operated in parallel for higher current?
Yes, the TPS6287B15VA0WRZVR supports stacked operation via SYNC_OUT and MODE/SYNC pins. Up to three devices can be daisy-chained to deliver up to 45A while sharing current and distributing thermal load-each unit maintains independent remote sensing and I²C telemetry for system-level monitoring.
What thermal protection features does the TPS6287B15VA0WRZVR include?
The TPS6287B15VA0WRZVR includes both thermal pre-warning (asserted at 150°C junction temperature) and thermal shutdown (at 170°C with 20°C hysteresis). These features provide early system-level alerts for thermal management and ensure safe, controlled shutdown before silicon damage occurs.
