What is TPS65287RHAT used for?
The TPS65287RHAT is designed for multi-rail power supply designs in single-board computers, ARM-based SoC platforms, and industrial embedded systems running from a 12 V bus or wide-input DC-DC stage. Its three integrated synchronous buck channels eliminate discrete power stage components for CPU core, I/O, and peripheral rails in a single IC. The integrated load switch and push-button control also make it well suited for tablet-style panels, embedded HMIs, and IoT gateways requiring soft power sequencing and user power control.

Frequently Asked Questions
What input voltage range does the TPS65287RHAT support, and what systems is it optimized for?
The TPS65287RHAT accepts an input voltage from 4.5 V to 18 V with a nominal 12 V operating point, making it ideal for industrial embedded boards, single-board computers, and ARM SoC platforms powered from a 12 V adapter or wide-range DC bus.
How much output current can each channel of the TPS65287RHAT deliver?
The TPS65287RHAT provides 3 A on buck converter channel 1 and 2 A each on channels 2 and 3, with the spec sheet noting peak current capability up to 3 A on channels 2 and 3 as well, enabling it to power a high-current CPU core and two peripheral rails from a single IC.
How does the integrated load switch in the TPS65287RHAT simplify power sequencing design?
The integrated load switch allows designers to sequence rail turn-on and turn-off under firmware or hardware control without adding a discrete P-MOSFET and gate driver, reducing BOM by 4-6 components and simplifying the power tree layout on densely populated SoC baseboards.
Does the TPS65287RHAT support efficient operation at light loads, and how is that achieved?
Yes, the TPS65287RHAT supports PFM (pulse-frequency modulation) control technique at light loads in addition to its primary PWM mode, automatically transitioning to PFM to reduce switching losses and quiescent current when load demand drops below approximately 300 mA per channel.
