Product Details
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 primary switch. No auxiliary winding or optocoupler is required for output voltage regulation. The MAX17690 is designed to operate over a wide supply range from 4. 5V to 60V. The switching frequency is programmable from 50kHz to 250kHz.
