Overview
The DCV010512DP-U/700, part of the DCV01 series from Texas Instruments, is a miniature, 1-W, 1500-Vrms isolated, unregulated DC/DC converter module. This device is designed to provide up to 1 W of isolated output power from a 5-V, 15-V, or 24-V input source. The DCV01 series is characterized by its high efficiency, typically up to 86%, achieved through advanced BiCMOS and DMOS process technology and highly integrated packaging. These converters are specified for operational isolation only and are not intended for safety isolation circuits requiring reinforced isolation.
