Product Summary

The ISL6313 is a two-phase PWM controller IC provides a precision voltage regulation system for advanced microprocessors. The integration of power MOSFET drivers into the ISL6313 marks a departure from the separate PWM controller and driver configuration of previous multiphase product families. By reducing the number of external parts, this integration is optimized for a cost and space saving power management solution.
