Analog Devices Inc. LTC7820 fixed ratio high voltage high power switched-capacitor/charge pump controllers provide a small and cost-effective solution for high power, non-isolated intermediate bus applications with fault protection. The devices include four N-channel MOSFET gate drivers to drive external power MOSFETs in a voltage divider, doubler, or inverter configurations. The devices achieve a 2:1 step-down ratio from an input voltage as high as 72V, a 1:2 step-up ratio from an input voltage as high as 36V, or a 1:1 inverting ratio from an input voltage up to 36V.
