IR3720 Datasheet (International Rectifier)

IR3720, Power Monitor IC

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 wind
