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

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.

Ordering Information

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.
