8mm) „ General Descriptions The AP1604 series are multi-functional step-down DC/DC converters with built-in speed, low ON resistance drivers.
It is capable to deliver 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 keeps at high efficiency for both light loads and large output current.
AP1604 can be soft-start with a proper capacitor connecte...
