LP1111 Dual Bootstrapped, 12V MOSFET Driver with Output Enable Datasheet
●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 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.
■Features
●All-In-One Synchronous Buck Driver
●Bootstrapped High-Side Drive
●One PWM Signal Generates Both Drives
●Anti-cross Conduction Protection Circuitry
●Available in SOP8 & TDFN8 Package
