Product details

Dual-output buck in a 14-pin exposed-pad TSSOP

The TPS54286PWPR is a dual-channel step-down (buck) regulator from Texas Instruments, each channel delivering 2 A continuous output from a 4.5 V to 28 V input rail. The output is adjustable via an external resistor divider from a 0.8 V reference up to 25.2 V, and the 630 kHz switching frequency balances inductor size against switching losses for typical 12 V or 24 V bus conversions.

Package and thermal interface

The surface-mount footprint suits single-sided or double-sided assembly; the 0.65 mm pin pitch is manageable with standard reflow profiles.

Frequently asked questions

Will TPS54286PWPR drop into a board designed for TPS65261RHBT?

No — the TPS65261RHBT is a triple-output buck with synchronous rectification in a different package (32-QFN), so the pinout and footprint are not compatible without a board spin.
