MAXREFDES113B#

The MAXREFDES113B# is an isolated 24V to 12V, 20W power supply reference design board. This reference design contains all the control circuitry and electric components required for designing 17V to 36V wide input, 20W output isolated flyback converter power supply. This power supply efficiently converts 24V into useful voltage rails at a variety of power levels. Every power rail is isolated with readily available transformer from multiple, global vendors providing for quick, convenient transformer selection. The design features MAX17596 peak current mode converter with flexible switching frequency. This design is set to switch at 200KHz. For EMI sensitive applications, the MAX17596 incorporates a programmable frequency dithering scheme enabling low EMI spread spectrum operation. This general purpose power solution can be used in many different types of power applications such as PLC, telecom, datacom power supplies, isolated battery chargers, servers & embedded computing.
