The MAX256 is a 3W H-bridge transformer driver with an input supply range from 3V to 5.5V. Integrated fault detection prevents overcurrent and over temperature conditions and integrated FETs provides a small and compact form factor. The MAX256 enables a designer an easy way to design a flexible isolated DC/DC power supply customized for their application needs. Applications for transformer driver based isolated DC/DC power supplies are suitable for industrial market like power meters, process control, fieldbus interface, as well as telecommunications equipment.
