DC-DC converters supply system robustness

The high-efficiency converters are designed to provide efficient, isolated power to circuits that require a bias supply with well-regulated output voltages.

The devices are ideal for a wide range of applications, including protection relays and smart breakers, PLC analogue input and output modules, patient monitoring, and isolated voltage and current sensing.

TI's UCC12050 and UCC12040 converters use a proprietary architecture to integrate a transformer and DC-DC controller, providing 500mW of isolated power with low electromagnetic interference (EMI) and high efficiency.

Both devices provide protection features for impressive system robustness, in addition to synchronisation capability and regulated 3.3V or 5V output options.

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

The UCC12040 converter comes with a 3kV_RMS basic isolation rating, surge capability of 8kV_PK, and a working voltage of 800V_RMS.

The UCC12050 and UCC12040 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 that provides an example of a proper board layout for rated isolation and EMI performance.
