onsemi NCP81075
The NCP81075 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 NCP81075 uses an on−chip bootstrap diode to eliminate the external discrete diode. The low−side and high−side are independently controlled and match to 4 ns between the turn−on and turn−off of each other.| Part No. | NCP81075 |
