MAXREFDES1084: Small 12W DC-DC Flyback Converter Using the MAX17596

The MAXREFDES1084 is a miniature, 24V output, isolated power supply that can deliver up to 0.5A of load current. The design uses the MAX17596 peak-currentmode controller in discontinuous-conduction mode (DCM) flyback topology running at 125kHz. The input voltage range of the MAX17596 is 4.5V to 36V. However, an extra bias winding from the transformer is used to power the controller. This allows the input operating voltage to go up to 60V for this design.
