- TYPICAL CHARACTERISTICS (PVIN = VIN = 12 V) The electrical characteristic data has been developed from actual products tested at 25°C. This data is considered typical for the converter. Applies to , , and . The temperature derating curves represent the conditions at which internal components are at or below the manufacturer's maximum operating temperatures. Derating limits apply to devices soldered directly to a 100 mm × 100 mm six-layer PCB with 1 oz. copper. Applies to , , and .
