The device is a high-voltage converter that smartly integrates an 800 V rugged power MOSFET with PWM current-mode control.This IC is capable of meeting more stringent energy-saving standards as it has very low consumption and_operates in burst mode under light load. The device features an adjustable extra power timer (EPT) that enables the IC to sustain overload conditions for a few seconds. The integrated HV startup， sense FET and_oscillator with jitter allow the advantage of using minimal components in the application. The device features high-level protections like dual-level OCP， output overvoltage， short-circuit， and_thermal shutdown with hysteresis. After the removal of a fault condition， the IC is automatically restarted.
