Overview

The NCP81145 is a high performance dual MOSFET gate driver optimized to drive the gates of both high-side and low-side power MOSFETs in a synchronous buck converter. It can drive up to 3nF load with a 25ns propagation delay and 20ns transition time.Adaptive anti-cross-conduction and power saving operation circuit can provide a low switching loss and high efficiency solution for notebook systems.The UVLO function guarantees the outputs are low when the supply voltage is low.

  • Industrial based power applications
  • Faster rise and fall times
  • Adaptive anti-cross-conduction circuit
  • Zero cross detection function
  • Output disable control turns off both MOSFETs
  • Undervoltage lockout
  • Power saving operation under light load conditions
