DCR010503U

The Texas Instruments DCR010503U is an isolated DC DC converter module designed for commercial ITE applications. It provides a single regulated 3.3V output from a 4.5V minimum input, delivering up to 300mA (1W) of output power. The converter includes control features such as enable with active high logic, remote on/off functionality, over-temperature protection (OTP), and short-circuit protection (SCP) for reliable operation.

Housed in a compact 28-SOIC (0.295", 7.50mm Width) package with 12 leads, the device has a supplier device package of 12-SOP. The surface mount package measures 17.9mm in length, 10.3mm in width, and 2.5mm in height, making it suitable for space-constrained designs. The operating temperature range spans from -40°C to 85°C, allowing use in various environmental conditions.

This isolated module simplifies the design of isolated power rails by integrating the transformer and control circuitry into a single component. The remote on/off feature enables power sequencing and low-power standby modes. With its commercial temperature rating and protection features, the DCR010503U is well-suited for powering low-voltage digital circuits, isolated sensors, and communication interfaces in industrial and commercial equipment.
