FUNCTIONAL DESCRIPTION
V IG ( R CS 1 + R CS 2 )
Please refer to the Functional Description Diagram
below. Power flow from the buck converter is the
product of output voltage times the current I L flowing
through the inductor.
Average power is measured with the aid of
International Rectifier’s proprietary TruePower?
circuit. Voltage, current, or the product of voltage Vo
and current is digitized over the interval of interest
and ported to the OUTPUT register. The VCS pin is
maintained at an average voltage equal to Vo.
I L
The full-scale voltage that can be measured is V FS .
The full-scale positive current that can be measured
is
I FS = ? . (1)
R T DCR
Full-scale current capability is designed by specifying
the external circuit values of equation 1.
The full scale power P FS that can be measured is the
product of full-scale voltage and full scale current.
