Taking in account only the consumption through the IC.
A great care should be taken to the maximum power consumption : VREC can be increased to 12.6V if the DC current flowing
through the head is reduced. This can be done by increasing R1 value. VREC can be reduced as long as voltage on Pin
IOUT does not fall below 1V (to avoid output stage saturation).
