An integrated design combining a fixed-frequency current mode controller and a 700V MOSFET.Dynamic Self-Supply (DSS) to eliminate the need for an auxiliary winding.Low standby power consumption (less than 50 mW at no-load).Protection features like overload, short-circuit, and Over-Voltage Protection (OVP).Fixed switching frequencies (65, 100, or 130 kHz).Frequency jittering for low EMI.Peak current capability up to 1.5A at 25°C.Internal 1 ms soft-start.Direct optocoupler connection for feedback.Operating junction temperature range of -40°C to +150°C.Pb-Free design.
