DESCRIPTION
The DCP02 series is a family of 2W, unregulated, isolated DC/DC converters. Requiring a minimum of external components and including on-chip device protection, the DCP02 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 power densities of 79W/in3 (4.8W/cm3) for the 14-PDIP, and 106W/in3 (6.5W/cm3) for the SO-28(1). This combination of features and small size makes the DCP02 suitable for a wide range of applications.
NOTE: (1) SO-28 version available January, 2000.
