IR3720 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 I2C. 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.
