Product Description
  • Product Description:
  • KP3221DP is a high-performance, low-cost offline PWM control power switch with a fixed 12V output. It integrates a 650V high-voltage MOSFET and a high-voltage startup circuit, supports buck and buck-boost topologies, and uses multi-mode PWM control to provide excellent line and load regulation while eliminating audible noise. The device also includes comprehensive protection features and is intended for low-power offline power supply applications.
