AP65452 (Not Recommended for new design)

The AP65452 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 AP65452 features programmable soft-start, UVLO, OTP and OCP to protect the circuit.

 

This IC is available in SO-8EP package.
