Dual Bootstrapped 12 V MOSFET Driver

Overview

The ADP3118 is a dual, high voltage MOSFET driver optimized for driving two N-channel MOSFETs, which are the two switches in a nonisolated synchronous buck power converter. Each of the drivers is capable of driving a 3000 pF load with a 25 ns propagation delay and a 25 ns transition time. One of the drivers can be bootstrapped and is designed to handle the high voltage slew rate associated with floating high-side gate drivers. The ADP3118 includes overlapping drive protection to prevent shoot-through current in the external MOSFETs.

  • Multiphase CPU supplies
  • Single-supply synchronous buck converters
  • Desktop computers
  • All in one synchronous buck converter
  • One PWM generates both drives
  • Anti cross-conduction protection circuitry
  • Bootstrapped high side driver
  • Output disable control turns off both MOSFETs to float output
  • Optimized for low gate charge MOSFETs
