TYPICAL APPLICATION CIRCUIT
DESCRIPTION
The IR3720 measures the output voltage and inductor
current of low-voltage DC-to-DC converters and reports
the average power over a user specified time interval as
a digital word on the I 2 C. The output current is
measured across a current sensing resistor or indirectly
across the inductor’s DCR winding resistance.
Additionally, the current measurement method is also
applicable to multiphase converters.
The real time voltage and current signals are multiplied,
digitized, and averaged over a user selectable
averaging interval providing Patent Pending
TruePower? measurement of highly dynamic loads.
