SLVSAY4B –JULY 2011–REVISED MAY 2012

4.5V to 18V Input, 5-A Synchronous Step-Down Converter with

Eco-Mode™

Check for Samples: TPS54528

FEATURES

DESCRIPTION

The TPS54528 is an adaptive on-time D-CAP2™

mode synchronous buck converter. The TPS54528

enables system designers to complete the suite of

various end-equipment power bus regulators with a

cost effective, low component count, low standby

current solution. The main control loop for the

TPS54528 uses the D-CAP2™ mode control that

provides a fast transient response with no external

compensation components. The adaptive on-time

control supports seamless transition between PWM

mode at higher load conditions and Eco-mode™

operation at light loads. Eco-mode™ allows the

TPS54528 to maintain high efficiency during lighter

load conditions. The TPS54528 also has a proprietary

circuit that enables the device to adopt to both low

equivalent series resistance (ESR) output capacitors,

such as POSCAP or SP-CAP, and ultra-low ESR

ceramic capacitors. The device operates from 4.5-V

to 18-V VIN input. The output voltage can be

programmed between 0.76 V and 6 V. The device

also features an adjustable soft start time. The

TPS54528 is available in the 8-pin DDA package,

and designed to operate from –40°C to 85°C.
