MAXREFDES112#: ISOLATED 24V TO 12V 10W
FLYBACK 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 for 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. In addition, boards are available
for purchase; most boards feature through-hole pins for immediate board placement and
accelerated prototyping.
MAXREFDES112# is an efficient flyback topology with 24V input, and a 12V output at
10W of power (0.8A). The design features the MAX17596, a peak-current-mode converter
with flexible switching frequency. This entire circuit fits on a 20.3mm (0.8in) x 59.7mm
(2.35in) board.
