Description

The AP65552 is an adaptive constant on-time mode synchronous

buck converter providing high efficiency, excellent transient response

and high DC output accuracy for low-voltage regulation in digital

TV and monitor.

The constant-on-time control scheme handles wide input/output

voltage ratios and provides low external component count. The

internal proprietary circuit enables the device to adopt both low

equivalent series resistance (ESR) output capacitors, such as

SP-CAP or POSCAP and ultra-low ESR ceramic capacitors.

The AP65552 features programmable soft-start, UVLO, OTP and

OCP to protect the circuit.

This IC is available in SO-8EP package.
