Power supply reference designs built by experts

Maxim MAXREFDES116 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 quick, convenient transformer selection. Each design has been tested for load and line regulation, as well as efficiency and transient performance. The device is an efficient active-clamp topology design with 24V input, and a 5V output at 40W of power (8A). The design features the power supply, an active-clamp, current-mode PWM controller optimised for industrial supplies. This entire circuit fits on a 20mm × 70mm board.
