3.3V to 5V Input, 6A, D-CAP+ Mode Synchronous Step-Down Converter with 2-Bit VID - TPS51461

TPS51461 (ACTIVE)

3.3V to 5V Input, 6A, D-CAP+ Mode Synchronous Step-Down Converter with 2-Bit VID

Description

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.

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

Features

  • Integrated FETs Converter w/TI Proprietary D-CAP+™ Mode Architecture
  • 6-A Maximum Output Current
