The UCC12040 is a high-density, low-EMI, 3-kVRMS basic isolation DC/DC module designed by Texas Instruments. This module features optimized integrated transformer technology, allowing for efficient power conversion in a compact form factor. With an input voltage range of 4.5V to 5.5V, the UCC12040 offers selectable output voltages of 5.4V, 5.0V, 3.7V, and 3.3V, with an output power of 500mW. The module boasts a peak efficiency of 60%, ensuring minimal power loss during operation. It also offers excellent line and load regulation, with typical values of 1% and 1.5% respectively, resulting in stable output voltages across varying input and output conditions. The UCC12040 meets CISPR32 Class B EMI limits without the need for ferrite beads on a 2-layer PCB, making it ideal for applications where electromagnetic interference suppression is critical. In addition, the UCC12040 features spread spectrum modulation (SSM), which helps to reduce electromagnetic interference further by spreading the energy over a wider frequency range. This modulation technique ensures compliance with stringent EMI standards while maintaining efficient power conversion. One of the key highlights of the UCC12040 is its robust isolation barrier, with an isolation rating of 3kV, providing a high level of safety and protection for sensitive electronic components. This isolation barrier ensures that the input and output circuits are fully separated, preventing the risk of electrical shock or damage due to voltage transients. Overall, the UCC12040 is a reliable and high-performance DC/DC module that offers efficient power conversion, low electromagnetic interference, and robust isolation capabilities, making it suitable for a wide range of industrial and consumer electronic applications. Its compact size, high efficiency, and EMI compliance make it an ideal choice for powering sensitive electronics in space-constrained environments where reliability and performance are crucial.
