AP2203

一、General Description
The AP2203 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. With the AP2203 Series, a step-up switching regulator can be configured by using an external coil and capacitor. A protection circuit turns off the built-in MOS FET when the voltage at the CONT pin exceeds the limit to prevent it from being damaged. This feature, along with the mini package and low current consumption, makes the AP2203 Series ideal for applications such as the power supply unit of portable equipment
