Digital power chipset from TI intelligently optimizes dead time to deliver industry's best efficiency
Texas Instruments introduced 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. 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. For more details, see www.ti.com/UCD7138-pr.
Accurate control of dead time in the synchronous rectifiers helps minimize power losses and reduces the risk of MOSFET failure. The UCD3138A and UCD7138 chipset use body-diode voltage information in fast digital control algorithms to dynamically optimize dead-time and compensate for power-stage component variations without calibration or screening during mass production. This helps telecom and server end-equipment manufacturers more easily bring to market energy-efficient 80 PLUS Titanium-grade power supplies, which saves energy costs to information technology service providers.
