STR2W152D and STR2W153D
Current Mode Control PWM Regulator ICs For Switching Power Supplies
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 < 25 mW at no load ▫ Normal load operation: PWM switching ▫ Light load operation: Standby mode (Burst oscillation) • Soft Start function: reduces stress on internal power MOSFET and output rectifier diode
