THERMAL DERATING CURVES

Measurements are done on IR3447 Evaluation board. PCB is a 6 layer board with 2 oz copper, FR4 material.

Vin=PVin=12V, Vout =1.2V, VCC=internal LDO (6.8V), Fs = 600kHz

Vin=PVin=12V, Vout =5.0V, VCC=internal LDO (6.8V), Fs = 600kHz

Note: International Rectifier Corporation specifies current rating of SupIRBuck devices conservatively. The

continuous current load capability might be higher than the rating of the device if input voltage is 12V typical and

switching frequency is below 600kHz. However, the maximum current is limited by the internal current limit and

designers need to consider enough guard bands between load current and minimum current limit to guarantee

that the device does not trip at steady state condition.
