DESCRIPTION
The DCP01B series is a family of 1W, unregulated,
isolated DC/DC converters. Requiring a minimum of
external components and including on-chip device
protection, the DCP01B series provides extra features
such as output disable and synchronization of switch-
ing frequencies.
The use of a highly integrated package design results
in highly reliable products with a power density of
40W/in3 (2.4W/cm3). This combination of features
and small size makes the DCP01B suitable for a wide
range of applications.
