DESCRIPTION

The DCP0105 family is a series of high efficiency, 5V

input isolated DC/DC converters. In addition to 1W

nominal galvanically isolated output power capability,

the range of DC/DCs are also fully synchronizable.

The devices feature thermal shutdown, and overload

protection is implemented via watchdog circuitry.

Advanced power-on reset techniques give superior

reset performance and the devices will start into any

capacitive load up to full power output.

The DCP0105 family is implemented in standard-

molded IC packaging, giving outlines suitable for high

volume assembly.
