TIDA-00711 Design is a compact, low cost, high efficiency, dual output, 50W, isolated DC-DC converter solution designed for use in Uninterruptable Power Supplies (UPS), energy storage banks and battery powered systems that require regulated and isolated power for internal operation. This reference design is an isolated SEPIC converter implemented using the wide input, current mode controller LM5020. The design is low cost due to minimal external component count compared to standard flyback designs realized with 384x series controllers. Additionally, The design operates at high switching frequency of 300kHz, resulting in smaller magnetics and high power density solution. TIDA-00711 design has built-in protections for output overcurrent, and input under-voltage protection. The hardware is tested to meet conducted emission norm EN55011/22 Class A.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
