Rectifier controller from Zetex said to optimise flyback converter design

Zetex Semiconductors has introduced a dedicated rectifier controller for driving MOSFETs so that they perform as ‘ideal diodes’ in synchronous flyback converters ranging from 50 to 150W. The ZXGD3101 enables designers to replace lossy Schottky diodes with surface mount MOSFETs to achieve higher efficiency, less heat generation, a reduction in power supply size and weight and a simplification of overall circuit design.

Gate drivers switch power MOSFETs and IGBTs faster than IC alternatives says Zetex

Zetex Semiconductors has announced a series of bipolar gate drivers for switching MOSFETs and IGBTs in power supplies and motor drives. Capable of sinking currents up to 9A, the low cost ZXGD3000 series enables faster charging and discharging of gate capacitances than is possible with gate driver ICs, resulting in more rapid switching times and greater circuit efficiency.
