TI introduces Green Rectifier controller for 5V power supplies
Texas Instruments has introduced a new power management controller and driver for standard and logic level N channel mosfets used for low voltage, secondary side synchronous rectification. The UCC24610 Green Rectifier controller has been designed to improve power supply efficiency as much as 5%, and reduce primaryside power loss in 5V ac/dc adapters and bias supplies.
The 600kHz rectifier is said to provide power saving features and design flexibility not available from traditional diode rectifier solutions. According to TI, its micro sleep current, automatic light load management and synchronous wake up features help maximize efficiency. The device also uses drain to source voltage sensing and support flyback and LLC resonant converters, in a bid to give designers greater flexibility.
