Power-management controller for standard MOSFETs

A Texas Instruments product story

Edited by the Electronicstalk editorial team Dec 22, 2010

Texas Instruments has introduced a 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 improves power-supply efficiency by as much as five per cent and reduces primary-side power loss in 5V AC/DC adapters and bias supplies.

The 600kHz UCC24610 Green Rectifier provides power-saving features and design flexibility not available from traditional diode rectifier solutions.

Its micro-sleep current, automatic light-load management and synchronous wake-up features help maximise efficiency.

The UCC24610 uses drain-to-source voltage sensing to support flyback and LLC resonant converters, as well as other power architectures, to give designers greater flexibility.

Features: small size and minimal external component count; high performance and efficiency - micro-power sleep current, automatic light-load management and synchronous wake-up from light-load conditions; system protection - device will shut down MOSFET if short or excessive 'on time' occurs; design flexibility - can be biased directly for a 5V output without external regulator.
