Digital Power Chipset Optimizes Dead Time And Efficiency

Digital Power Chipset Optimizes Dead Time And Efficiency
Texas Instruments Inc.

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
