Features and Benefits

  • All-in-one synchronous buck driver
  • Bootstrapped high-side drive
  • One PWM signal generates both drives
  • Anti-crossconduction protection circuitry
  • OD for disabling the driver outputs

Product Details

The ADP3650 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 45 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 ADP3650 includes overlapping drive protection to prevent shoot-through current in the external MOSFETs.

The OD pin shuts off both the high-side and the low-side MOSFETs to prevent rapid output capacitor discharge during system shutdown.

The ADP3650 is specified over the temperature range of −40°C to +85°C and is available in 8-lead SOIC_N and 8-lead LFCSP packages.
