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.
