High Voltage Synchronous Rectified Buck MOSFET Driver
FN9047 Rev 0.00 Nov 2001
The ISL6205 is a high-voltage, high-frequency, dual MOSFET driver specifically designed to drive two N-Channel power MOSFETs in a synchronous rectified buck converter topology in mobile puting applications. This driver bined with an ISL6223 or other Intersil Multi-Phase Buck PWM controllers forms a plete 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...
