1 / 8 page  LP1110-00 Oct.-2017 Email: marketing@lowpowersemi.com www.lowpowersemi.com Page 1 of 8 Preliminary Datasheet LP1110 Dual Bootstrapped, 12V MOSFET Driver with Output Enable General Description The LP1110 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 MOSFETgate 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 undervoltage 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.
