Preliminary Datasheet LP1111
Dual Bootstrapped, 12V
MOSFET Driver with Output Disable
General Description
The LP1111 is a single Phase 12V
MOSFET gate driver optimized to drive the gates of both high-side and low-side power
MOSFETs in a synchronous buck converter.
With a wide operating
voltage range, high or low side
MOSFET gate drive
voltage can be optimized for the best efficiency. Internal adaptive non-overlap circuitry further reduces switching losses by preventing simultaneous conduction of both
MOSFETs.
The floating top driver design can accommodate VBST
voltages as high as 35V, with transient
voltages as high as 40V. Both gate outputs can be driven low by applying a low logic level to the enable (EN) pin. An under
voltage lockout 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.
