Texas Instruments Presents the First Integrated Circuit

Texas Instruments (TI) has 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.

TIIts 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. Download the white paper, “Power Through the Isolation Barrier: The Landscape of Isolated DC/DC Power Supplies” to learn more about this new family of reinforced isolated DC/DC bias supplies.

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

Key features and benefits of the UCC12050

  • Small size, increased power density: Available in a 16-pin small-outline integrated circuit (SOIC) package measuring 10.3 mm by 10.3 mm by 2.65 mm, the UCC12050 offers 60% efficiency – twice that of competing devices of similar size – and twice the power density of comparative isolated power modules. Delivering 0.5 W in the new architecture improves reliability, enables a small BOM and simplifies board layout.
  • Ultra-low EMI: The UCC12050’s integrated transformer with very low primary-to-secondary capacitance is optimized for EMI performance, and its quiet control scheme makes it easier for engineers to have their designs pass Comité International Spécial des Perturbations Radioélectriques (CISPR) 32 Class B EMI tests, with margin, on a two-layer printed circuit board. The solution also eliminates external filter components such as low-dropout regulators and ferrite beads normally required to meet EMI certification, which significantly reduces component selection and design time.
  • Reinforced isolation, wide temperature range: The UCC12050’s reinforced isolation with 8-mm creepage and clearance is used for protection and robustness against ground potential differences. Its high efficiency and extended -40°C to 125°C operating temperature range deliver more power in extreme conditions. Read the technical article, “Isolation 101: How to find the right isolation solution for your application,” to learn how reinforced isolation and the UCC12050, in particular, can help save time, effort, space and possibly cost over other isolated bias supply solutions.
