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