STR3A153 - PWM Off-Line Switching Regulator ICs

Download the STR3A153 datasheet PDF. This datasheet also covers the STR3A151 variant, as both devices belong to the same pwm off-line switching regulator ics family and are provided as variant models within a single manufacturer datasheet.

General Description

STR3A100 series are power ICs for switching power supplies, incorporating a power MOSFET and a current mode PWM controller IC in one package.

Key Features

  • Current mode PWM control.
  • Built-in Random Switching function: reduces EMI noise, simplifies EMI filters, and cuts cost by external part reduction.
  • Built-in Slope Compensation function: avoids subharmonic oscillation.
  • Built-in Leading Edge Blanking (LEB) function.
  • Auto Standby function: ▫ Input power, PIN < 10 mW at no load with low power consumption shunt regulator ▫ Normal load operation: PWM switching ▫ Light load operation: Standby mode (Burst osc.
