General Characteristics

Conditions: 25 °C case, 75% rated load and specified input voltage range unless otherwise specified.

[a]

Does not exceed IPC-9592 derating guidelines. At 70 °C ambient, full power operation may exceed IPC-9592 guidelines, but does not exceed

component ratings, does not activate OTP and does not compromise reliability.
