MAXREFDES111 Power Supply Reference Design

Analog Devices MAXREFDES111 Isolated Flyback Power Supply Reference Design includes an efficient flyback topology with 24V input and a 5V output at 2W of power (0.4A). This reference design is a series of isolated, industrial power supply reference designs. 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 reference design features the MAX17498B, a peak-current-mode converter with an internal N-channel MOSFET switch. This entire circuit fits on a 36mm x 20mm board.
