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.
Features of DK1203 Controller IC :
- Integrated PWM controller with high-voltage MOSFET
- Wide input voltage range (85V–265V AC)
- Low standby power for energy-efficient designs
- Frequency jittering function to reduce EMI
- Built-in over-voltage, over-current, and thermal protection
- Internal startup and feedback circuitry
- DIP-8 through-hole package for easy prototyping and soldering
