LPSemi/微源半导体 LP1111 SOP8/TDFN8 具有输出启用功能的双自举12V MOSFET驱动器
General Description
The LP1111 is a single phase 12V MOSFET gatedriver optimized to drive the gates of both high-sideand low-side power MOSFETs in a synchronous buckconverter.With a wide operating voltage range, high or low sideMOSFET gate drive voltage can be optimized for thebest efficiency. Internal adaptive non-overlap circuitryfurther reduces switching losses by preventingsimultaneous conduction of both MOSFETs.The floating top driver design can accommodate VBSTvoltages as high as 35V, with transient voltages ashigh as 40V. Both gate outputs can be driven low byapplying a low logic level to the enable(EN) pin. Anundervoltage lockout function ensures that both driveroutputs are low when the supply voltage is low, and aThermal Shutdown function provides the IC withover-temperature protection.
Features

◆ Bootstrapped High-Side Drive
◆ One PWM Signal Generates Both Drives
◆ Anti-cross Conduction Protection Circuitry
◆ Available in SOP8 & TDFN8 Package
Applications
◆ Multiphase Desktop CPU Supplies
◆ Single-supply Synchronous Buck Converters
