STR-A6051M - Current Mode Control PWM Regulator

Download the STR-A6051M datasheet PDF. This datasheet also covers the STR-A60xxM variant, as both devices belong to the same current mode control pwm regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The STR-A60xxM series are power ICs for switching power supplies, incorporating a power MOSFET and a current mode PWM controller IC.

Key Features

  • Small DIP8 package with 8 to 24 W power output 230 VAC.
  • Current Mode PWM control with 67 kHz switching frequency.
  • Built-in Random Switching function, reducing EMI noise, and simplifying EMI filters, and therefore reducing cost.
  • Built-in Slope Compensation function, avoiding subharmonic oscillation.
  • Built-in Auto Standby function (Input Power, PIN < 25 mW at no load) ▫ Normal operation: PWM mode ▫ Light load operation: Standby mode (burst oscillation).
  • Built-in Audi.
