DP2539 DIP8 PWM Power Switch IC

DP2539 DIP8 PWM Power Switch IC

DP2539A is a high performance offline PWM power switch for low power AC/DC charger and adapter applications. It operates in primary-side sensing and regulation. Consequently, opto-coupler and TL431 could be eliminated. High Precision Constant Voltage (CV) and Constant Current (CC) control are integrated as shown in the figure below.DP2539A offers comprehensive protection coverage with auto-recovery features including Cycle-by-Cycle current limiting, VDD Over Voltage Protection (VDD OVP), short circuit protection, built-in leading edge blanking, VDD under voltage lockout.

DNA solutions, Nashik has various types of IC's. Check out our complete collection of  IC's.

If you are in Nashik you can buy this Electronic Component at our local shop at New CBS, Nashik or you can place order online and get it delivered at your doorstep anywhere in India.
