STR2W153D - Current Mode Control PWM Regulator

Download the STR2W153D datasheet PDF. This datasheet also covers the STR2W152D 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 STR2W152D and STR2W153D 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 < 25 mW at no load ▫ Normal load operation: PWM switching ▫ Light load operation: Standby mode (Burst oscillation).
  • Soft Start function: re.
