DCR010503U

The DCR01 series is a range of high - efficiency, input - isolated, output - regulated DC/DC converters. In addition to the electrically isolated 1W nominal output power capability, this series of DC/DC converters also offers features such as ultra - low output noise, thermal protection, and high precision. The DCR01 series devices combine these features with a small size, making them suitable for a variety of applications. They are also an easy - to - use solution for applications that require signal path isolation. The DCR01 series of power modules offer isolation from a regulated power supply operating from a choice of input voltages. The DCR01s provide a regulated 3.3 - V or 5 - V output voltage at a nominal output power of 1 W or above. The DCR01 devices include a low dropout linear regulator internal to the device to achieve a well - regulated output voltage. The DCR01 devices are specified for operational isolation only. The circuit design uses an advanced BiCMOS and DMOS process.
