Diodes Incorporated AP65453SP | Demoboard AP65453SP-EVM

Description

The AP65453 is an adaptive 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 adaptive on-time control supports seamless transition between continuous conduction mode (CCM) at higher load conditions and discontinuous conduction mode (DCM) at lighter load conditions.DCM allows AP65453 to maintain high efficiency at light load conditions.

Features

The AP65453 also features programmable soft-start, UVLO, OTP, OVP and OCP to protect the circuit.
