KP3211 - PWM control power switch

Download the KP3211 datasheet PDF. This datasheet also covers the KP3210 variant, as both devices belong to the same pwm control power switch family and are provided as variant models within a single manufacturer datasheet.

General Description

KP321X family is a high performance Switch Mode Power Supply Switcher for low power off-line application with minimum components in typical buck solution.

This family has built-in high break down voltage MOSFET to withstand high surge input.

Key Features

  • Integrated with 650V Power MOSFET and HV Startup Circuit.
  • Multi-Mode Control with Audio Noise Free Operation.
  • Supports Buck and Buck-Boost Topologies.
  • Default 12V Output with FB floated.
  • Less than 50mW Standby Power.
  • Green Mode Operation for High Efficiency.
  • Good Line and Load Regulation.
  • Built-in Soft Start.
  • Build in Protections:.
  • Over Load Protection (OLP).
  • Cycle-by-Cycle Current Limiting (OCP).
  • Output OVP.
  • VDD OVP, UVLO & Clamp.
