ISL6208 and ISL6208B are high -frequency dual MOSFET drivers, which are optimized to topology at the synchronous rectifier BUCK converter. They are particularly suitable for mobile computing applications to require high efficiency and excellent thermal performance. These drivers combine a internal multi -phase buckpwm controller to form a complete single -stage core voltage advanced mobile micro -processor regulator solution. ISL6208 and ISL6208B are the same but different packaging. The description in this data table is based on ISL6208 and is also suitable for ISL6208B. ISL6208 has a typical sinking current of 4A. This current can maintain lower MOSFETs closed along the end. This prevent high DV/DT phase voltage. Working voltage and 30V matching MOSFET's penetrating voltage computer power supply is commonly used.

ISL6208 also has a three -state PWM input, working with the multi -phase PWM controller of Intersil, which will prevent negative voltage output during the CPU closure. This feature eliminates the generally in a microprocessor power system. Use 6208 Island. Each driver can drive 3000PF load with 8NS transmission delay and 10 -nan seconds. Bootstrapping is a diode implemented with internal Schottky. This reduces system costs and complexity, while allowing higher -performance MOSFETs. Adaptable penetration protection is integrated to prevent MOSFET performed at the same time. In the ISL6208, a diode simulation function improves the efficiency of converter under light load conditions. This function also allows monotonous start to premium output. When the diode simulation is enabled, the driver will allow the inductance current to reach zero, and then turn off the low side MOSFET grid.
