产品信息
产品概述
The LM5021MM-2/NOPB is an 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. It features include an ultra-low (25µA) 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 and so forth). Additional features include under-voltage lockout, cycle-by-cycle current limit, hiccup mode overload protection, slope compensation, soft-start and oscillator synchronization capability. This high performance 8-pin IC has total propagation delays less than 100ns and a 1MHz capable oscillator that is programmed with a single resistor.
