General Description

The AP2201 Series is a CMOS PFM-control step-up switching regulator that mainly consists of a reference voltage source, an oscillator, and a comparator, enabling products with a low ripple over a wide range, high efficiency, and high output current.

Products with a fixed duty ratio of 75 % （ Lower Output Voltage ） or 88%(Higher Output Voltage) are also available.

With the AP2201 Series, a step-up switching regulator can be configured by using an external coil, capacitor, and diode.
