STR3A151, STR3A152, STR3A153, STR3A154, STR3A155
PWM Off-Line Switching
Regulator ICs
Features and Benefits
• 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 oscillation)
