Note 1: Power dissipation is 400 mW when mounted as recommended. Derate at 3.2 mW/°C for operation above 25 °C. Power dissipation is
200 mW when in Free Air. Derate at 1.6 mW/°C for operation above 25 °C.
Note 2: This IC is a frequency-controlled DC-DC converter; thus the value is varied by condition.
