General Descriptions
The AP1609 is high efficient step-up DC/DC
converter. Large output current is possible having
a built in internal N channel MOSFET, and using an
external coil and diode.
Output voltage is programmable with 1.23V of
standard voltage supply internal, and using
externally connected components, output voltage

can be set up at will.
With a 300KHz switching frequency, the size of the
external components can be reduced. Control
switches from PFM to PWM during light loads with
the AP1609

and the series
is highly efficient from light loads to large output
currents.
During stand-by time
