Dual Bootstrapped, 12 V MOSFET Driver

Overview

The ADP3110A is a dual, high voltage MOSFET driver optimized for driving two N-channel MOSFETs, the two switches in a nonisolated synchronous buck power converter. Each driver is capable of driving a 3000 pF load with a 25 ns propagation delay and a 30 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 ADP3110A 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
  • OD for disabling the driver outputs
  • Meets CPU VR requirement when used with Flex-Mode™ controller
