STR-W6251D - PWM Off-Line Switching Regulator ICs

General Description

STR-W6200D series are power ICs for switching power supplies, incorporating a power MOSFET and a current mode PWM controller IC in one package.

Key Features

  • TO-220 fully-molded package with 6 pins.
  • Current mode PWM control.
  • PWM and frequency modulation functions: reduces EMI noise, simplifies EMI filters, and cuts cost by external part reduction.
  • Built-in Slope Compensation circuit: avoids subharmonic oscillation.
  • Automatic Standby Mode function (Input Power < 40 mW at no load) ▫ Normal operation: PWM mode ▫ Light load operation: Standby mode (burst oscillation).
  • Built-in Audible Noise Suppression function during Stand.
