DCR010503U/1K Description

Short technical summary and product information.

The Texas Instruments DCR010503U/1K is an isolated DC/DC converter module designed for commercial ITE applications. It provides a regulated 3.3V output from a 4.5V minimum input voltage, delivering up to 300mA (1W). The module includes protective features such as remote on/off control, over-temperature protection (OTP), and short-circuit protection (SCP). The converter operates over a temperature range of -40°C to 85°C.

 

This converter is housed in a 28-SOIC surface-mount package with 12 leads (supplier package 12-SOP), measuring 17.9mm x 10.3mm x 2.5mm. It is ideal for space-constrained designs requiring isolated power conversion. The device is RoHS3 compliant and REACH unaffected, with an MSL rating of 1 (unlimited).
