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.
