Description

General part information

NCP81085 Series

The NCP81085 is a high performance dual MOSFET gate driver optimized to drive the gates of both high and low side power MOSFETs in a synchronous buck converter. The NCP81085 uses an on−chip bootstrap diode to eliminate the external discrete diode. A high floating top driver design can accommodate HB voltage as high as 180 V. The low−side and high−side are independently controlled and match to 4 ns between the turn−on and turn−off of each other. Independent Under−Voltage lockout is provided for the high side and low side driver forcing the output low when the drive voltage is below a specific threshold.
