TI DCR021205P-U

The DCR02 series is a range of high-efficiency, input-isolated, output-regulated DC/DC converters. In addition to the electrically isolated 2W nominal output power capability, this series of converters also offers ultra-low output noise and high precision. The DCR02 series uses a standard molded package and provides a standard JEDEC outline, suitable for high-volume assembly. They are manufactured using the same technology as standard device packages, thus achieving extremely high reliability.

The DCR02 series of power modules offer isolation from a regulated power supply operating from 12-V or 24-V inputs. The DCR02s provide a regulated 5-V output voltage at a nominal output power of 2 W. The DCR02 devices include a low dropout linear regulator internal to the device to achieve a well-regulated output voltage. The DCR02 devices are specified for operational isolation only. The circuit design uses an advanced BiCMOS and DMOS process.
