The AP65355 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 AP65355 features programmable soft-start, UVLO, OTP, high voltage tolerance EN pin, Power Good and OCP to protect the circuit. This IC is available in DFN3030-10 package.
