This driver combined with an ISL6223 or other Intersil Multi-Phase Buck PWM controllers forms a complete single-stage core-voltage regulator solution for advanced mobile microprocessors. The ISL6205 allows users to select a gate voltage ranging from 5V to 12V for the lower MOSFET in the synchronous rectified buck converter. Using a 12V gate voltage reduces the RDS(ON) and the conduction loss in the MOSFET. The upper gate is required to run at 5V. The ISL6205 features a three-state PWM input that, working together with any Intersil multiphase PWM controllers, will prevent a negative transient on the output voltage when th...
