The UCD3138A and UCD7138 embark as the first power management chipset with intelligent digital control and a unique body-diode sensing feature to optimize secondary-side synchronous rectification in next-generation ac/dc and isolated dc/dc power supplies. As per the company, the UCD3138A digital controller and UCD7138 low-side gate driver improve system efficiency and cut synchronous rectification MOSFET voltage stress in half compared to other digital-power solutions. Available now, the UCD7138 MOSFET driver is packaged in a six-pin QFN package and is priced at $1.10 each/1,000. The UCD3138A digital controller is packaged in a 40-pin QFN and is priced at $3.22 each/1,000. A datasheet is available at http://www.ti.com/product/UCD7138/datasheet
