6.10 Typical Characteristics

The maximum recommended average power safe operating area (SOA) at each VIN is determined by the lower value of the 1.5W limit (dotted line) and the corresponding thermal derating curve (solid line) at that input voltage. Ambient temperatures higher than 125oC is not recommended. The thermal derating power is acquired with an evaluation board similar to the EVM shown in the Layout Example section. Tshut represents the primary-side over-temperature shutdown rising threshold. As shown in the Electrical Characteristics table, the typical Tshut value is 160oC, and minimal Tshut value is 150oC. The SOA derating curve with both Tshut = 160oC and 150oC are provided below. The SOA curves under four common VDD-VEE settings, 15V, 18V, 22V, and 25V are characterized. In each SOA curve, the input voltage is swept from 9V to 18V. To represent a worst-case condition with Tshut = 150oC, the test is done in a shieded box to block circulating air in the thermal chamber.
