ISL6235
Advanced Triple PWM Only Mode and
Dual Linear Power Controller for Portable
Applications
The ISL6235 provides a highly integrated power control and
protection solution for five output voltages required in high-
performance 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 synchronous-
rectified 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 r
DS(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.
Two internal linear regulators provide +5V ALWAYS and
+3.3V ALWAYS low current outputs required by the
notebook system controller.
