AP65454 - Diodes

AP65454 650kHz ADAPTIVE COT STEP-DOWN CONVERTER

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 proprieta.
