Description

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.TheODpin 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.ApplicationsTelecom and datacom networkingIndustrial and medical systemsPoint of load conversion: memory, DSP, FPGA, ASIC
