Mouser is now stocking Texas Instruments’ UCC12050 and UCC12040 isolated dc-dc converters.

The devices supply isolated power to circuits that require a bias supply with regulated output voltages.ucc12050

They’re suitable for applications including protection relays and smart breakers, PLC analog input and output modules, patient monitoring, and isolated voltage and current sensing.

The UCC12050 and UCC12040 converters use a proprietary architecture to integrate a transformer and DC-DC controller, providing 500mW of isolated power while meeting CISPR32 class B EMI limits without ferrite beads across their load range on a 2-layer PCB.

The devices reach a peak typical efficiency of 60% at 80mA with an input voltage of 5V.

Both provide protection features in addition to synchronisation capability and regulated 3.3V or 5V output options.

The UCC12050 offers a 5kVRMS reinforced isolation rating, a surge capability of 10kVPK, and a working voltage of 1.2kVRMS.

The UCC12040 converter comes with a 3kVRMS basic isolation rating, surge capability of 8kVPK, and a working voltage of 800VRMS.

They have an operating temperature range from -40ºC to 125ºC and are certified to IEC60950-1, 62368-1 and 60601-1 end equipment standards. Both measure 10.3×7.5mm, offered in a SOIC package at a height of 2.65mm.

The converters are supported by the UCC12050EVM-022 evaluation module.

The module allows designers to evaluate the abilities and performance characteristics of the two converters, with an EVM layout for rated isolation and EMI performance.
