Description

General part information

TPS51461 Series

The TPS51461 is a fully integrated synchronous buck regulator employing D-CAP+™. It is used for up to 5-V step-down where system size is at its premium, performance and optimized BOM are must-haves.

This device fully supports Intel system agent applications with integrated 2-bit VID function.

The TPS51461 also features two switching frequency settings (700 kHz and 1 MHz), skip mode, pre-bias startup, programmable external capacitor soft-start time/voltage transition time, output discharge, internal VBST Switch, 2-V reference (±1%), power good and enable.
