Ordering Information
General Description
The AP1609 is a 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 (FB) 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 (PWM/PFM switchable) and
the series are highly efficient from light loads to large output
currents.
During stand-by time (CE pin “Low”), current consumption is
reduced to 1µA.
