I've found one from CIRRUS LOGIC ...
anything else?

power factor ic

Have a look at the circuit below ..
Instead of specil parts it uses common ICs ..
A brief description of this circuit you can find at:
**broken link removed**
Calculations of the power factor (VMcos[theta]/VM) can be done by any microcontroller with ADC .. not necessarily by ICL7106 chip ..
