Description

Circuit 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 circuit also uses U102 and Q101(and resistors etc etc…) as an external UVLO circuit. 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.
