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.
