APPLICATION NOTE 529
15V Input Converter Generates -185V at 50mA


Abstract:This design note shows how a 15V input flyback converter generates -185V at 50mA. The circuit uses the MAX668
step-up controller and a transformer to make a flyback converter.

Figure 1. This circuit uses the MAX668 and a transformer (which will need about a one-to-six turns ratio) to make a flyback
converter. The op amp inverts the
