5 Absolute Maximum Ratings
Stresses beyond those listed in Table 3 may cause permanent damage to the device. These are stress ratings only,
and functional operation of the device at these or any other conditions beyond those indicated in Table 4, “Electrical
Characteristics,” on page 6 is not implied. Exposure to absolute maximum rating conditions for extended periods may
affect device reliability.

1. Depending on actual PCB layout and PCB used measured on demoboard; for peak power dissipation during
flashing see document 'AS3647/47B Thermal Measurements'
2. P DERATE derating factor changes the total continuous power dissipation (P T ) if the ambient temperature is not
70oC. Therefore for e.g. T AMB =85oC calculate P T at 85oC = P T - P DERATE * (85oC - 70oC)
3. Pins LED_OUT1 connected to LED_OUT2 and capacitor C VOUT connected to VOUT1/2 and GND; both GND
pins connected together
4. Measured on AS3647/47B Demoboard.
