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.

Including a startup circuit and a standby function in the controller, the product achieves low power consumption, low standby power, and high cost-effectiveness in power supply systems, while reducing external components.

The products are provided in an industry standard DIP8 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.
