MAXREFDES121#: Isolated 24V to 3.3V 33W power supply

Maxim's power supply experts designed and built a series of isolated industrial power supply reference designs, each of which efficiently converts 24V to voltage rails at various power levels. Each power rail is isolated using commercially available transformers, making transformer selection quick and easy. Each design is tested for load and line regulation, as well as efficiency and transient performance.

Space-optimized boards are available for purchase. Each board features high-current pins and is designed to be mounted on a PCB like a module, further speeding development and production. All Maxim reference designs include BOMs, schematics, layout files, and Gerber files.
