If any of these ratings are exceeded during operation, the electrical characteristics of the device may be irreparably altered, in which case the reliability and lifetime of the device can no longer be guaranteed. Moreover, any exceeding of the ratings during operation may cause breakdown, damage and/or degradation in other equipment. Applications using the device should be designed so that no absolute maximum rating will ever be exceeded under any operating condition. Note 1: Please use output voltage within the above absolute maximum rating, 40 V, in which includes back-EMF voltage. Note 2: The output current may be subject to the duty cycle, ambient temperature and heatsink. Ensure that the junction temperature does not exceed 150°C (max).
