High voltage industrial application power supply size
Maximize efficiency by reducing size by up to 80%


Texas Instruments (TI) announced on the 12th that it is releasing the 500mW DC/DC converter UCC12050.

The UCC12050 is housed in a 16-pin SOIC package measuring 10.3 × 10.3 × 2.65 mm and offers 60% efficiency, which is twice that of competing products of the same size, and twice the power density of comparable isolated power modules.

The 0.5W architecture improves reliability, reduces BOM, and simplifies board layout.

Integrating a transformer with low primary-to-secondary capacitance, the UCC12050 optimizes EMI blocking performance while enabling engineers to develop designs that pass CISPR 32 Class B EMI testing through low-noise control techniques and a two-layer PCB.

It simplifies component selection and design by eliminating external filter components such as LDO regulators and ferrite beads required to pass EMI certification.

UCC12050 is Reinforced insulation with 8 mm creepage and clearance distances provides protection against ground potential differences and robustness. Operating temperature ranges from -40 to 125°C enable increased power density even under harsh conditions.

Suitable for any industrial application requiring isolation, the UCC12040 is a power converter that provides 3kVrms basic isolation with the same features.

The UCC12050 and UCC12040 are available in volume production and through TI and authorized distributors. They are priced at $3.90 and $3.15, respectively, in quantities of 1,000.

The UCC12050EVM-022 evaluation module for product evaluation is available for $99 on TI.com.
