Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.

Absolute maximum ratings are stress ratings only and functional device operation is not implied.

2. Output current rating is limited by input voltage, duty cycle, and ambient temperature. Under any set of

conditions, do not exceed a junction temperature of +125°C.
