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 (700kHz and 1MHz), 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.
The TPS51461 is available in a 4mm × 4mm, 24-pin, QFN package (Green RoHs compliant and Pb free) and is specified from 0°C to 85°C.
