ISL8103

DATASHEET ISL8103 Three-Phase Buck PWM Controller with High Current Integrated MOSFET Drivers FN9246 Rev 1.00 July 21, 2008 The ISL8103 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 mulitphase 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 provided for...
