ADP3110A

Dual Bootstrapped, 12 V
MOSFET Driver with Output
Disable
The ADP3110A is a single Phase 12 V MOSFET gate drivers
optimized to drive the gates of both high-side and low-side power http://onsemi.com
MOSFETs in a synchronous buck converter. The high-side and
low-side driver is capable of driving a 3000 pF load with a 25 ns MARKING
propagation delay and a 30 ns transition time. DIAGRAMS
