ISL6226
Advanced PWM and Linear Power
Controller for Portable Applications
The ISL6226 provides power control and protection for two
user selected output voltages required in high-performance
notebook PC applications. The IC integrates a fixed,
selectable frequency pulse-width-modulation (PWM)
controller and a 3A LDO linear regulator controller with
monitoring and protection circuitry in a single 24 lead SSOP
package.
The PWM controller regulates the battery input voltage to a
user selected output voltage. Synchronous converter and
hysteretic operation at light loads contribute to a high
efficiency over a wide range of input voltage and load
variation. Efficiency can be 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 internal linear regulator controller provides a user
selected high current output from an unregulated input with
user selected current limit.
