Beschreibung

The AP65454 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 AP65454 also features programmable soft-start, UVLO, OTP, OVP and OCP to protect the circuit.The AP65454 operates in continuous conduction mode (CCM) in light load conditions for better EMI performance. AP65353 and AP65355 are the options for light load efficiency enhancement.This IC is available in SO-8EP package.
