APPLICATION NOTE 1115
Isolated SLIC supply


Abstract: This application note shows a power supply that generates three isolated voltages for SLICs. The isolated power supply
uses a boost controller, the MAX668, with a transformer in flyback typology for -24V, and -72V outputs, and isolates the
feedback signal with an optocoupler. A linear voltage regulator, the MAX8867, provides the 3.3V output.
