The LM5021 off-line pulse width modulation (PWM) controller contains all of the features needed to implement highly efficient off-line single-endedflyback and forward power converters using currentmode control. The LM5021 features include an ultra- low (25 µA) start-up current, which minimizes power losses in the high voltage start-up network. A skip cycle mode reduces power consumption with light loads for energy conserving applications (ENERGY STAR®, CECP, etc.). Additional features includeunder-voltage lockout, cycle-by-cycle current limit, hiccup mode overload protection, slope com- pensation, soft-start and oscillator synchronizationcapability. This high performance 8-pin IC has total propagation delays less than 100nS and a 1MHz capable oscillator that is programmed with a singleresistor.
Remark: BOM and Schematics are added with main pdf.
