36V Transformer Driver Simplies Isolated
Power
MAX13256
The MAX13256 enables a simple and exible approach to the design of an isolated
DC-DC supply. The MAX13256 operates from a wide 8V to 36V DC supply and
can deliver up to 10W of isolated power. Maxim’s transformer drivers provide
system designers with greater exibility by using an external transformer’s
winding ratio to allow the selection of virtually any isolated output voltage.
The MAX13256 H-bridge transformer driver oers higher integration with
short-circuit protection and overtemperature protection to help prevent
system level failures. Packaged in a space-saving (3mm x 3mm) TDFN,
this integrated device reduces design complexity and lowers BOM cost,
giving system designers the simplest solution for isolated power-supply
circuits in industrial, smart metering, and medical applications.
