IPM6210A
Precision Dual PWM Controller And
Linear Regulator for Notebook CPUs
The IPM6210A is a highly integrated power controller which
provides a complete power management solution for mobile
CPUs. The IC integrates two PWM controllers and a linear
regulator as well as monitoring and protection circuitry into a
single 28-lead plastic SSOP package. The two PWM
controllers regulate the microprocessor core and I/O
voltages with synchronous-rectified buck converters, while
the linear regulator powers the CPU clock.
The IPM6210A includes 5-bit digital-to-analog converter
(DAC) that adjusts the core PWM output voltage from
0.925V
DC
to 2.0V
DC
and conforms to the Intel Mobile VID
specification. The DAC setting may be changed during
operation to accommodate Dual-Mode processors. Special
measures are taken to provide such a transition with
controlled rate in a specified 100
μ
s. A precision reference,
remote sensing, and a proprietary architecture with
integrated processor mode-compensated “droop” provide
excellent static and dynamic core voltage regulation. The
second PWM controller has a fixed 1.5V output voltage and
powers the I/O circuitry. Both PWM controllers have
integrated feedback loop compensation that dramatically
reduces number of the external components. At nominal
loads PWM controllers operate at a fixed frequency of
300kHz. At light loads when the filter inductor current
becomes discontinuous, controllers operate in a hysteretic
mode. Out-of-phase operation of two PWM controllers to
reduce input current ripple is provide in both modes of
operation. The linear regulator uses an internal pass device
to provide 2.5V for the CPU clock generator.
The IPM6210A monitors all the output voltages. A single
Power-Good signal is issued when soft start is completed
and all outputs are within ±10% of their respective set points.
A built-in overvoltage protection for the core and I/O outputs
forces the lower MOSFETs on to prevent output voltages
from going above 115% of their settings. Undervoltage
protection latches the chip off when any of three outputs
drops below 75% of the set value. The PWM controller's
overcurrent circuitry monitors the output current by sensing
the voltage drop across the lower MOSFETs. If precision
overcurrent protection is required, an external current-sense
resistor may optionally be used.
