STR-A60xxHDescriptionThe STR-A60xxH series are power ICs for switching power supplies , incorporating a power MOSFET and a Current mode PWM controller IC. 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 STR-A60xxH internal MOSFET has a VDSS of 650 V(min) or 700 V(min), and an RDS(on) of or with a frequency of 100 kHz. power output is rated at 10 or 15 W at 230 VAC input and 8 or 13 W at wide input range (85 to 265 VAC).The device is provided in an industry-standard DIP-8 package, with pin 6 removed for increased isolation. Features and benefits Small DIP8 package with10 to 15 W power output 230 VAC Current Mode PWM Control with 100 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 Bui
