Texas Instruments introduced the first integrated circuit (IC) developed with a new proprietary 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 breakthrough integrated transformer 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.

TI will demonstrate the UCC12050 in booth No. 1001 at the Applied Power Electronics Conference (APEC) in New Orleans, Louisiana, March 15-19, 2020.

This new high-density isolated power converter, the latest industry-leading device in TI’s power-management portfolio, offers small size and ease of use for any industrial application requiring isolation. Additionally, the new UCC12040 provides all of the same benefits with 3-kVrms 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.
