60 Hz sine wave, and it is well within the limit for a 20-year

service life.

The dc working voltage limit is set by the creepage of the

package as specified in IEC 60664-1. This value can differ for

specific system level standards.

THERMAL ANALYSIS

For the purpose of thermal analysis, the ADP1031 die are

treated as a thermal unit, with the highest junction temperature

reflected in the θJA values from Table 7. The value of θJA is based

on measurements taken with the devices mounted on a JEDEC

standard, 4-layer board with fine width traces and still air.

Under normal operating conditions, the ADP1031 operates at

a full load across the full temperature range without derating

the output current. However, following the recommendations

in the PCB Layout Considerations section decreases thermal

resistance to the PCB, allowing increased thermal margins in

high ambient temperatures. Each switching regulator in the

ADP1031 has a thermal shutdown circuit that turns off the dc-

to-dc converter and the outputs when a die temperature of

approximately 150°C is reached. When the die cools below

approximately 135°C, the ADP1031 dc-to-dc converter outputs

turn on again.
