TI's EMI-optimized integrated transformer technology miniaturizes isolated power transfer into IC-sized packaging

03/10/2020

Texas Instruments (TI) 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.

The main technical characteristics of 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. 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.
