AP65453 Description
The AP65453 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 ponent count. The internal proprietary circuit enables the device to adopt both low equivalent...
