TI Unveils Its New Transformer Technology

TI has introduced its first IC developed with a new integrated transformer technology: a 500-mW high-efficiency isolated DC/DC converter with the industry’s lowest electromagnetic interference (EMI), the UCC12050.

Its 2.65-mm height enables designers to reduce their solution volume by as much as 80% compared to discrete solutions and 60% compared to power modules – with twice the efficiency of competing devices.

Built for industrial performance, the UCC12050’s 5-kVrms reinforced isolation and 1.2-kVrms working voltage protect against high-voltage spikes in systems such as industrial transport, grid infrastructure and medical equipment.

TI’s technology enables high-density isolated DC/DC power conversion, while maintaining low EMI.

The single-package, surface-mount architecture gives designers an easy-to-use, low-profile IC that reduces the bill of materials (BOM), and efficiently operates across a wide temperature range.

An EMI-optimized, low capacitance transformer and quiet control scheme streamline EMI compliance while providing a reliable solution with options for reinforced or basic isolation.

The UCC12050 and UCC12040 are available in volume production from TI and authorized distributors in a 16-pin, 10.3-mm-by-10.3-mm-by-2.65-mm SOIC package.

Pricing starts at US$3.90 and US$3.15, respectively, in 1,000-unit quantities. Engineers can evaluate this product with the UCC12050EVM-022 evaluation module, available on TI.com for US$99.
