Do you know the technology of miniaturizing power transmission isolation into IC size packaging?

What is EMI-optimized integrated transformer technology? Do you know it? Texas Instruments Incorporated (NASDAQ: TXN) today introduced the first integrated circuit (IC) developed using new proprietary integrated transformer technology: an industry-leading 500mW high-efficiency isolated DC/DC converter UCC12050 with lower electromagnetic interference (EMI). Its 2.65mm height helps designers reduce solution size (80% compared to discrete solutions and 60% compared to power modules) and is twice as efficient as competing devices. The UCC12050 is designed for improved industrial performance, with its 5kVrms reinforced isolation and 1.2kVrms operating voltage protecting systems from high voltage spikes (such as in industrial transportation, 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 provides designers with an easy-to-use, low-profile integrated circuit that reduces the bill of materials (BOM) and operates efficiently over a wide temperature range. EMI-optimized, low-capacitance transformers and quiet control solutions simplify EMI compliance while providing a reliable solution with a choice of enhanced or basic isolation. Download the white paper, "Power Through the Isolation Barrier: An Overview of Isolated DC/DC Power Supplies" to learn more about this new family of reinforced isolated DC/DC bias power supplies.

Key Features and Benefits of UCC12050

Small size and increased power density: The UCC12050 is available in a 16-pin small outline integrated circuit (SOIC) package measuring 10.3 mm × 10.3 mm × 2.65 mm, providing 60% efficiency, twice that of competing devices of the same size, and also Twice the power density of the relative isolated power module. Using 0.5W in the new architecture improves reliability, reduces the bill of materials, and simplifies board layout.

Lower EMI: The UCC12050’s integrated transformer with lower primary to secondary capacitance optimizes EMI performance, and its silent control scheme makes it easier for engineers to get their designs to pass the International Special Committee on Radio Interference (CISPR) 32 Class B electromagnetic interference Test as it leaves margin on both layers of PCB. This solution also eliminates external filter components typically required to meet EMI certification, such as low dropout regulators and ferrite beads, significantly reducing component selection and design time.

Reinforced Isolation, Wide Temperature Range: The UCC12050’s reinforced isolation with 8mm creep and clearance is used to protect and resist ground potential differences. Its high efficiency and wide operating temperature range (-40°C to 125°C) deliver more power under extreme conditions.

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

Packaging and availability

The UCC12050 and UCC12040 are available now in volume from Texas Instruments and its authorized distributors in a 16-pin 10.3mm x 10.3mm x 2.65-mm SOIC package. Engineers can use the UCC12050EVM-022 evaluation module to evaluate this product. The above is the analysis of EMI optimized integrated transformer technology, I hope it can help you.
