49: Maxim H-Bridge Transformer Driver Enables Simple and Flexible Isolated DC-DC Designs

Maxim Integrated Products introduced the MAX13256, an H-bridge transformer driver with a wide input-voltage range for isolated power supplies. According to Maxim, using this simple solution, engineers can quickly design a highly efficient (up to 90%) isolated dc-dc converter. The MAX13256 drives a transformer’s primary coil with up to 300mA of current from an 8V to 36Vdc supply which can deliver up to 10W of isolated power. Users can choose their own transformer winding ratio which defines the output voltage, thus allowing the selection of virtually any isolated output voltage. This robust supply range eliminates external voltage regulation. Integrated protection features prevent system-level failures.
