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 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.
