MAXREFDES116# ISOLATED 24V TO 5V 40W POWER SUPPLY
Overview
Maxim’s power supply experts have designed and built 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. As with all Maxim reference
designs, the BOM, schematics, layout files, and Gerber files are all available for download in the
Design Resources tab. In addition, boards are available for purchase; most boards feature through-
hole pins for immediate board placement and accelerated prototyping.
MAXREFDES116# is an efficient active-clamp topology design with 24V input, and a 5V output at
40W of power (8A). The design features the MAX17599, an active-clamp, current-mode PWM
controller optimized for industrial supplies. This entire circuit fits on a 20mm × 70mm board.
