3 Description

The TPS53513 device is a small-sized, synchronous

buck converter with an adaptive on-time D-CAP3

control mode. The device offers ease-of-use and low

external-component count for space-conscious power

systems.

This device features high-performance integrated

MOSFETs, accurate 0.5% 0.6-V reference, and an

integrated boost switch. Competitive features include

very low external-component count, fast loadtransient

response, auto-skip mode operation,

internal soft-start control, and no requirement for

compensation.

A forced continuous conduction mode (FCCM) helps

meet tight voltage regulation accuracy requirements

for performance DSPs and FPGAs. The TPS53513

device is available in a 28-pin VQFN package and is

specified from –40°C to +85°C ambient temperature.
