ISL68301 Functional Diagram
Description
This device is no longer supported and is not recommended for new designs.
The ISL68300 with integrated MOSFET drivers and ISL68301 with PWM output simplify designing power supplies for data center, wired and wireless communications, and factory automation equipment. The ISL68300 can drive discrete external MOSFETs directly, while the ISL68301 pairs with Renesas’ smart power stages or DrMOS power stages to create a complete voltage regulator solution.
