MAXREFDES114D#

The MAXREFDES114D# is an isolated 24V to 5V, 10W power supply reference design. It is an efficient active clamp topology design with 24V input and 5V output at 10W of power (2A). The design features MAX17599, an active clamp current mode PWM controller optimized for industrial supplies. The IC contains all the control circuitry required for the design of wide input isolated forward converter industrial power supplies. It features active-clamp transformer reset topology for forward converters. This reset topology has several advantages including reduced voltage stress on the switches, transformer size reduction due to larger allowable flux swing and improved efficiency due to elimination of dissipative snubber circuitry. 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 and embedded computing.
