KP311AWPA - High Performance Low Cost Off-line PWM Power Switch

General Description

KP311AWP is a low cost, highly integrated PWM power switch for non-isolated buck applications.

KP311AWP combines a 500V power MOSFET with the ON/OFF PWM controller in one chip.

The IC can achieve high precision 5V default Output at universal AC input.

Key Features

  • Integrated with Rectifier diode, Freewheeling diode, Feedback diode.
  • Integrated with 500V MOSFET and High Voltage Startup Circuit.
  • High Precision 5V Default Output.
  • No External Rsense needed, Low BOM Cost.
  • Support Ultra-low Input Voltage (>12V).
  • Support Buck Topology.
  • On/OFF Peak Current Mode Control.
  • Less than 50mW Standby Power.
  • Built-in 31KHz Oscillator with Frequency Shuffling.
  • Built-in Soft Start.
  • Very Low VDD Operation Current.
