The AP1604 series are multi-functional step-down DC/DC converters with built-in speed, low ON resistance drivers. It is capable of delivering more than 800mA output current with external coil, diode and capacitor. Output voltage is set-up by the external resistors (±2.5% accuracy). The 600KHz AP1604 that can work out with small value external components comes out more compact board. The device switches to and works under PFM mode with light loads. It remains at high efficiency for both light loads and large output current. AP1604 can be soft-started with a proper capacitor connected between CE/SS pin and ground. The stand-by current is less than 2uA when CE/SS pin is at “LOW” status. The device is forced to switch off as the voltage at that pin is lower than the stipulated voltage.
