MAXREFDES111C#

The MAXREFDES111C# is an isolated 24V input, 5V output and 2W flyback power supply reference design board. It has an efficient flyback topology with 400mA output current. The design features MAX17498B peak current mode converter with internal N-channel MOSFET switch. The MAX17498B is a peak current mode controller for design of wide input voltage flyback and boost regulators. The reference design operates over an 18V to 36V input voltage range and provides up to 400mA (plus 20% overhead) at 5V output. This entire circuit fits on a 36mm x 20mm (1.4in x 0.8in) board. In addition, through hole pins on the bottom side of the module allows quick and easy integration of this power converter into the main system. Pins are 15mm (0.6in) from power to ground and 28mm (1.1in) from the input side to the output side. It is typically used in PLCs, telecom and datacom power supplies.
