9.4.2 External Voltage Control
9.5 Thermal Performance
Thermal testing of the unit was conducted in a thermal chamber under convectional
cooling. The unit was placed horizontally. The volume of convectional cooling was
limited by a cardboard box with dimensions 12” x 10” x 9” (Height x Width x Depth). This
box was used to prevent forced air-cooling of the unit by the thermal chamber’s fan. The
temperature of the PeakSwitch was measured by attaching a thermocouple to the
device’s tab. The output diode’s temperature was monitored in an identical manner. The
unit’s output voltage was approximately 12.5 V during testing with a load of 3 A.
