SBVS012E − DECEMBER 2000 − REVISED DECEMBER 2007
Miniature, 1W Isolated
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 switching
frequencies.
The use of a highly-integrated package design results in
highly reliable products with a power density of 40W/in
3
(2.4W/cm
). This combination of features and small sizes
makes the DCP01B suitable for a wide range of
applications.
