LT1680 High Power DC/DC Step-Up Controller FEATURES s s DESCRIPTION The LT ®1680 is a high power, current mode switching power supply controller optimized for boost topologies. The IC drives N-channel MOSFET switches for DC/DC converters in applications up to 60V input. A high current gate drive output handles up to 10,000pF gate capacitance, enabling the construction of high power DC/DC converters. Current sense common mode range up to 60V allows current sensing to be referenced to the input supply, eliminating the need for sense blanking circuits. The LT1680 incorporates programmable average current limiting allowing accurate limiting of DC current in the magnetics, independent of ripple current . User adjustable slope compensation provides stable operation at duty cycles up to 90%.
