APPLICATIONS
The ISL6235 provides a highly integrated power control and protection solution for five output voltages required in highperformance notebook PC applications. The IC integrates three fixed frequency pulse-width-modulation (PWM) controllers and two linear regulators along with monitoring and protection circuitry into a single 24 lead SSOP package. The two PWM controllers that regulate the system main 5V and 3.3V voltages are implemented with synchronousrectified buck converters. Synchronous rectification insures high efficiency over a wide range of input voltage and load variation. Efficiency is further enhanced by using the lower MOSFET’s rDS(ON) as the current sense element. Input voltage feed-forward ramp modulation, current-mode control, and internal feed-back compensation provide fast and stable handling of input voltage load transients encountered in advanced portable computer chip sets. The third PWM controller is a boost converter that regulates a resistor selectable output voltage of nominally 12V.
