MAXREFDES115#: ISOLATED 24V TO 5V 20W POWER
SUPPLY
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 for quick, convenient
transformer selection. Each design has been tested for load and line regulation, as well as
efficiency and transient performance.
MAXREFDES115# is an efficient active clamp topology design with 24V input, and a 5V at
4A (20W) of power. The design features the MAX17599, an active clamp, current-mode
PWM controller optimized for industrial supplies; this entire circuit fits on a 20mm x 55mm
board. As with all Maxim reference designs, the BOM, schematics, layout files, Gerber files
are all available. In addition, all boards feature through-hole pins for immediate board
placement and accelerated prototyping, and are available for purchase.
