General DescirptionOC3001
The OC3001 is a single Phase 12V
MOSFET gate drivers optimized to drive the
gates of both high−side and low−side power
MOSFETs in a synchronous buck converter.
The high−side and low−side driver is capable
of driving a 3nF load with a 25ns propagation
delay and a 30ns transition time.OC3001
With a wide operating voltage range, high
or low side MOSFET gate drive voltage can
be optimized for the best efficiency. The
internal adaptive non-overlap circuit further
reduces the switching losses by preventing
simultaneous conduction of both MOSFETs.
The floating top driver design can
accommodate BST voltages as high as 40V,OC3001
with transient voltages as high as 48V. Both
gate outputs can be driven low by applying a
low logic level to the OD pin. An UVLO
function ensures that both driver outputs are
low when the supply voltage is low, and a
Thermal Shutdown function provides the IC
with over-temperature protection.OC3001
OC3001 is available in SOP8 and DFN8
package.
