To extend operating thermal range
Fins on horizontal heat sinks run from the
input pins toward the output pins. Fins on
vertical heat sinks 90 ° to this.
Absolute Maximum Ratings
Stress in excess of the absolute maximum ratings may cause performance degradation, adversely affect
long term reliability or cause permanent damage to the converter.
