KP3222DP is a low-cost offline PWM-controlled power switch IC designed for compact AC-DC power supply applications. It integrates a 650V high-voltage MOSFET and high-voltage startup circuit, reducing external components and simplifying power supply design.
The device uses multi-mode PWM control technology to improve efficiency, line/load regulation, and standby performance. It supports Buck and Buck-Boost converter topologies and provides stable fixed 12V output power conversion for low-power applications.
KP3222DP includes multiple protection functions such as overload protection, cycle-by-cycle current limiting, output over-voltage protection, VDD protection, and thermal protection, making it suitable for reliable offline power supply designs.
