VIPER28LN - PWM-Regler, 3A, 800V, 60kHz,A DIP7

Features800 V avalanche-rugged power MOSFET allowing achieving ultra wide-range input VacEmbedded HV startup and sense FETPWM current-mode controllerOCP with selectable threshold (IDlim) and 2nd OCP with higher value (IDMAX) to protect the IC from transformer saturation or short-circuit of the secondary diode30 mW no-load consumption at 230 VacTwo operating frequencies:- 60 kHz (L type) or 115 kHz (H type)Jittered frequency reduces the EMIExtra power timer (EPT) blanks the overload current for few secondsOutput overvoltage protection with tight tolerance and digital noise filterSoft-start reduces the stress during startup and increases IC lifetimeAutomatic restart after a fault conditionThermal shutdown increases system reliability and IC lifetimeApplicationsAuxiliary power supply for consumer and home equipmentPower supply for energy meters and data concentratorsAC-DC adapters
