AP65550 Datasheet 650khz Adaptive Cot Step-down Converter

Manufacturer: Diodes Incorporated

Overview: AP65550 5A, 18V, 650kHz ADAPTIVE COT STEP-DOWN CONVERTER.

General Description

The AP65550 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 ponent count.

The internal proprietary circuit enables the device to adopt both low equivalent series resistance (ESR) output capacitors, such as SPCAP or POSCAP and ultra-low ESR ceramic capacitors.

Key Features
