AP1551 Datasheet (Anachip) - 150KHz Dual Channel 2A PWM Buck DC/DC Converter

AP1551, 150KHz Dual Channel 2A PWM Buck DC/DC Converter

The AP1551 is monolithic IC designed for dual channel step-down DC/DC converters, and own the ability of driving a 2A load each channel without additional transistor component.

Due to reducing the number of external component, the board space can be saved easily.

The external shutdown function can b
