The ISL6308A is a three-phase PWM control IC with integrated
MOSFET drivers. It provides a precision
voltage regulation system for multiple applications including, but not limited to, high current low
voltage point-of-load converters, embedded applications and other general purpose low
voltage medium to high current applications.The integration of power
MOSFET drivers into the controller IC marks a departure from the separate PWM controller and driver configuration of previous multi-phase product families. By reducing the number of external parts, this integration allows for a cost and space saving power management solution.
Output
voltage can be programmed using the on-chip DAC or an external precision reference. A two bit code programs the DAC reference to one of 4 possible values (0.6V, 0.9V,1.2V and 1.5V). A unity gain, differential amplifier is provid...
