Isolated power supply reference designs built by experts

Maxim MAXREFDES115 Isolated Power Supply Reference Designs, available from Mouser, are a series of isolated, industrial power supply reference designs. These reference designs were designed and built by power supply experts. Each of these power supplies efficiently converts 24V into useful voltage rails at a variety of power levels. Every power rail is isolated with a readily available transformer from multiple, global vendors, providing for quick, convenient transformer selection. Each design has been tested for load and line regulation, as well as efficiency and transient performance. The design is an efficient active clamp topology with 24V input and a 5V output at 4A (20W) of power. The design features the MAX17599, a low-IQ wide-input-range active-clamp current-mode PWM controller. This entire circuit fits on a 20mm x 55mm board.
