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
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.
