DK1203 AC-DC Switch Mode Power Controller IC - DIP-8

The DK1203 SMPS IC is a high-performance monolithic switch-mode power controller IC designed for low-power offline AC-DC applications. It combines a PWM controller with a built-in high-voltage power MOSFET in a compact DIP-8 package, making it ideal for small and efficient SMPS designs. It features low standby power, frequency jittering to reduce EMI, and integrated protection functions, making it a reliable solution for chargers, LED drivers, and auxiliary power supplies.
