Synchronous PolyPhase Boost Converter for Cool and Powerful Applications

Boost power conversion is important function in many industrial, automotive and commercial applications. Higher power level customers have to deal with issues of high ripple currents, high power dissipation and higher EMI levels.

The LTC3788 breaks new ground in boost converter technology, achieving the highest efficiency with synchronous PolyPhase operation. Two separate synchronous boost channels allow the part to be used in single or dual output applications. The part can be used in PolyPhase applications with 2-, 4- and 6-phases. Also, the LTC3788 circuits can be smaller and less expensive, thanks to low power dissipation in synchronous rectifiers. Overall, LTC3788 can significantly improve the performance of high current, high power, boost circuits.
