ISL6596

ISL6596 Synchronous Rectified MOSFET Driver The ISL6596 is a high frequency, MOSFET driver optimized to drive two N-Channel power MOSFETs in a synchronous buck converter topology. Combine this driver with the Renesas Multi-Phase Buck PWM controllers to form a complete single-stage core-voltage regulator solution with high efficiency performance at high switching frequency for advanced microprocessors. The IC is biased by a single low voltage supply (5V), minimizing driver switching losses in high MOSFET gate capacitance and high switching frequency applications. Each driver can drive a 3nF load with less than 10ns rise/fall time. Bootstrapping of the upper gate driver is implemented with an internal low forward drop diode, reducing implementation cost, complexity, and allowing the use of higher performance, cost effective N-Channel MOSFETs. Adaptive shoot-through protection is integrated to prevent both MOSFETs from conducting simultaneously. The ISL6596 features 4A typical sink curren...
