Features

* include: bootstrapping for high side drive supplies, asynchronous mode start up, power up sequencing to prevent latchups, individual soft start for each convertor, bootstrapped drivers for high side N-channel MOSFETs, input side current sensing, dual mode current limit with hiccup, enable and extern

Applications

* where efficiency is most important. Both converters are synchronized to prevent beat frequencies. The dual buck converters are also operated out of phase reducing input ripple, allowing for fewer input capacitors. High frequency operation up to 1.1 MHz reduces the size of output inductors and capaci
