AP65454
4A, 18V, 650kHz ADAPTIVE COT STEP-DOWN CONVERTER
Description
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 TVs and monitors.
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 as well as ultra-low ESR ceramic
capacitors.
The AP65454 also features programmable soft-start, UV...
