Note 2: All MAX16814A_ _ are 100% tested at TA = +125NC, while all MAX16814U_ _ and MAX16814B _ _ _ are 100% tested at
TA = +25°C. All limits overtemperature are guaranteed by design, not production tested.
Note 3: CS threshold includes slope-compensation ramp magnitude.
Note 4: Gain = δVCOMP/δVCS, 0.05V < VCS < 0.15V.
