SLUSBB5A –FEBRUARY 2013–REVISED JUNE 2013

22-V Input, 8-A or 10-A Converter

With Integrated FET

Check for Samples: TPS51363

FEATURES

DESCRIPTION

The TPS51363 is a high-voltage input, synchronous

converter with integrated FET, based on D-CAP2™

control topology, which enables fast transient

response and supports both POSCAP and all MLCC

output capacitors. TI proprietary FET technology

combined with TI leading-edge package technology

provides the highest density solution for single-output

power rail such as VCCIO and VDDQ for DDR

notebook memory, or any point-of-load (POL) in wide

application.

•

Input Voltage Range: 3 V to 22 V

Output Voltage Range: 0.6 V to 2 V

8-A or 10-A Integrated FET Converter

(see Table 1)

•

•

Switching Frequency: 400 kHz and 800 kHz

D-CAP2™ Architecture to Enable POSCAP and

All MLCC Output Capacitor Usage

The feature set includes switching frequency of 400

kHz and 800 kHz. Programmable soft-start time with

an external capacitor. auto skip, pre-bias startup,

integrated bootstrap switch, power good, enable and
