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.
