ISL6622A, VR11.1 Compatible Synchronous Rectified Buck MOSFET Drivers

DATASHEET ISL6622A VR11.1 Compatible Synchronous Rectified Buck MOSFET Drivers FN6601 Rev 2.00 March 19, 2009 The ISL6622A is a high frequency MOSF.

Features

* Dual MOSFET Drives for Synchronous Rectified Bridge
* Advanced Adaptive Zero Shoot-Through Protection
* 36V Internal Bootstrap Schottky Diode
* Diode Emulation For Enhanced Light Load Efficiency
* Bootstrap Capacitor Overcharging Prevention
* Support

Applications

* involving trade-offs between gate charge and conduction losses. To further enhance light load efficiency, the ISL6622A enables diode emulation operation during PSI mode. This allows Discontinuous Conduction Mode (DCM) by detecting when the inductor current reaches zero and subsequently turning off t
