a. Due to the SO-8 package power dissipation limitations, the input peak current is valid up to 85°C ambient temperature only on 4-oz copper
PCB. For >85°C ambient, derating is needed. For details, refer to footnote a at Absolute Maximum Ratings. For Input Power Derating Curve,
refer to the curve as shown in the following section.
