FEATURES AND BENEFITS
● Small DIP8 package with 8 to 24 W power output 230 VAC● Current Mode PWM control with 67 kHz switching frequency
● Built-in Random Switching function, reducing EMI noise, and simplifying EMI filters, and therefore reducing cost
● Built-in Slope Compensation function, avoiding subharmonic oscillation
● Built-in Auto Standby function (Input Power, PIN < 25 mW at no load) ▫ Normal operation: PWM mode ▫ Light load operation: Standby mode (burst oscillation)
● Built-in Audible Noise Suppression function during Standby mode
● Built-in Startup Circuit, reducing power consumption in standby operation, and eliminating external components.
● Bias-Assist function, improving startup operation, suppressing VCC voltage drop in operation, and allowing use of smaller VCC capacitor Continued on the next page…
DESCRIPTION
Including a startup circuit and a standby function in the controller, the product achieves low power consumption, low standby power, and high cost-effectiveness power supply systems with few external components.
