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.
