ISL6620, ISL6620A
VR11.1 Compatible Synchronous Rectified Buck MOSFET Drivers
FN6494 Rev 0.00 April 25, 2008
The ISL6620, ISL6620A is a high frequency MOSFET driver designed to drive upper and lower power N-Channel MOSFETs in a synchronous rectified buck converter topology. The advanced PWM protocol of ISL6620, ISL6620A is specifically designed to work with Intersil VR11.1 controllers and combined with N-Channel MOSFETs, form a complete core-voltage regulator solution for advanced microprocessors. When ISL6620, ISL6620A detects a PSI protocol sent by an Intersil VR11.1 controller, it activates Diode Emulation (DE) operation; otherwise, it operates in normal Continuous Conduction Mode (CCM) PWM mode.
