IPM6220A
Advanced Triple PWM and Dual Linear
Power Controller for Portable
Applications
The IPM6220A 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 and
hysteretic operation at light loads contribute to 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.

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is compatible with both SnPb and
Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J Std-020B.
