XL7015E1

XL7015E1 is the TO-252-5 ordering code for the XLSEMI XL7015 step-down converter, listed word-for-word in the ordering information of the current XLSEMI datasheet (Rev 1.6) at 2,500 pieces per reel, the E1 being the lead-free finish. XLSEMI publishes no lifecycle grading for the part; the code stands in the maker’s current ordering table. It holds its feedback voltage between 1.225 V and 1.275 V (1.25 V typical) so the output is divider-set, switches at 120 kHz minimum, 150 kHz typical and 180 kHz maximum, limits switch current at 1 A, draws quiescent current of 2.5 mA typical and 5 mA maximum with shutdown current of 85 µA typical and 200 µA maximum, and is characterised at 86 % typical efficiency at a 36 V input and 15 V, 0.4 A output. One rating needs care: the Rev 1.6 headline and absolute-maximum figures raise the input ceiling to 100 V, but the electrical table still specifies a 5 V to 80 V operating input range - design to the 5 V to 80 V operating range and treat anything above it as a survival rating, not a working rail. The selection point is a sub-ampere rail straight from high-voltage buses - e-bike, industrial auxiliary and appliance supplies - in a tab package that solders to copper pour for cooling. Parameters verified against the XLSEMI XL7015 datasheet Rev 1.6 (ordering information and electrical characteristics).
