STR2W152D - Current Mode Control PWM Regulator

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.
