(1)

A. Characteristic data has been developed from actual products tested at 25

°C. This data is considered typical data for the converter.

(2)

B. Load current is increased proportionally from both outputs, up to the indicated maximum value of each respective output.

(3)

C. SOA curves represent the conditions at which internal components are at or below the manufacturer's maximum operating

temperatures. Derating limits apply to modules soldered directly to a 4 in.

× 4 in. double-sided PCB with 1 oz. copper.
