MAX17690 Datasheet (Maxim Integrated) - No-Opto Isolated Flyback Controller

MAX17690, No-Opto Isolated Flyback Controller

The MAX17690 is a peak current mode, fixed-frequency switching controller specifically designed for the isolated flyback topology operating in Discontinuous Conduction Mode (DCM).

The device senses the isolated output voltage directly from the primary-side flyback waveform during the off-time of the
