Key features
800 V avalanche-rugged power MOSFET allowing achieving ultra wide-range input V_ac Embedded HV startup and sense FET PWM current-mode controller OCP with selectable threshold (I_Dlim) and 2^ndOCP with higher value (I_DMAX) to protect the IC from transformer saturation or short-circuit of the secondary diode 30 mW no-load consumption at 230 V_ac Two operating frequencies: 60 kHz (L type) or 115 kHz (H type) Jittered frequency reduces the EMI Extra power timer (EPT) blanks the overload current for few seconds Output overvoltage protection with tight tolerance and digital noise filter Soft-start reduces the stress during startup and increases IC lifetime Automatic restart after a fault condition Thermal shutdown increases system reliability and IC lifetime
