General 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 current-mode 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 include under-voltage lockout, cycle-by-cycle current limit, hiccup mode o...
