DK124 Power Management IC 24W DIP 8 Package

DK124 Power Management IC 24W DIP 8 Package

The DK124 is a highly integrated Power Management IC (PMIC) designed for off-line switch mode power supply (SMPS) applications up to 24 watts. It combines a high-voltage power MOSFET, a PWM controller, and essential protection features into a single DIP-8 package, minimizing external components and simplifying power supply design.

Engineered for high efficiency and low standby power, the DK124 supports universal AC input (85V–265V) and is suitable for isolated and non-isolated topologies such as flyback and buck converters. It ensures stable output regulation, high reliability, and comprehensive protection, making it ideal for consumer electronics and industrial control systems.
