AP2201 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 parator, 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...
