Power management controller and MOSFET driver chip for AC/DC adapters

Texas Instruments Incorporated (TI) 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. TI says the UCC24610 Green Rectifier controller improves power supply efficiency as much as five percent, and reduces primary-side power loss in 5-volt AC/DC adapters and bias supplies.

The 600-kHz UCC24610 Green Rectifier is touted to offer power-saving features and design flexibility not available from traditional diode rectifier solutions. Featured with micro-sleep current, automatic light-load management and synchronous wake-up, the UCC24610 uses drain-to-source voltage sensing to support flyback and LLC resonant converters and other power architectures.

Other features of UCC24610 include; the device will shut down MOSFET if short or excessive "on time" occurs and can be biased directly for a 5-V output without external regulator.
