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

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 100µs. 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.
