Description

The LM5021 off-line pulse width modulation (PWM) controller contains all of the features needed to implement highly efficient off-line single-ended flyback and forward power converters using currentmode control. The LM5021 features include an ultralow (25 µA) start-up current, which minimizes power losses in the high voltage start-up network.
