PMP7769, 700V - 860V input to 16.5V @ 0.5A Reference Design

PMP7769, Reference Design is a non isolated flyback converter. Vin is 700V to 800V max, converting to 16.5V out at a maximum current of 500mA. The design utilizes an external Error amplifier using an LMC7101 for feedback control. The LM5021 features include an ultra-low (25A) 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
