The Chipown AP8022A is a Switching Controllers DIP-8 in a RoHS package. It is a highly integrated monolithic low-power switch mode pulse-width modulation (PWM) controller. It is specifically designed for off-line and DC-to-DC converter applications. The device provides the industry's highest level of integration, reducing the number of discrete components and increasing performance for cost-effective, space-saving solutions. It features a wide range of output voltages and full protections, such as over voltage protection (OVP), under voltage protection (UVP), current limit, and over temperature protection (OTP). The device operates from an input voltage of 4.5V to 42V and provides a fold-back peak current-limit protection threshold. The AP8022A is ideal for powering CPU and other high current applications.
