L6565DTR ST AC-DC Controllers

The L6565DTR is a current-mode primary controller for flyback converters from STMicroelectronics in SO-8 package, specifically designed for off-line power supplies with wide input voltage range. For selection, verify supply voltage from 8V to 20V, low start-up current of 0.5mA typical, operating quiescent current of 3mA, switching frequency up to 70kHz, and operating temperature from -40°C to +150°C. Features include frequency foldback for standby power reduction in light-load conditions, overvoltage protection with safe auto-restart, low consumption for improved efficiency, and cycle-by-cycle current limiting. Ideal for AC-DC adapters for laptops, printers, and battery chargers, auxiliary power supplies in industrial equipment, low-cost flyback converters, and any off-line switching power supply requiring simple, robust control with good efficiency across load range.
