XL4016E1

XL4016E1 is the TO-220-5 ordering code for the XLSEMI XL4016 buck DC-DC converter, written word-for-word in the ordering information of the maker’s current English datasheet (Rev 1.2), which lists the code with marking XL4016E1 in the TO220-5L body in tube packing and identifies the E1 suffix as XLSEMI’s lead-free / RoHS mark. Its feedback voltage is 1.225 V minimum, 1.25 V typical and 1.275 V maximum over an 8 V to 40 V input and a 0.5 A to 8 A load range, its oscillator runs at 144 kHz minimum, 180 kHz typical and 216 kHz maximum, its switch current limit is 10 A typical, its switch on-resistance is 40 mΩ typical and 50 mΩ maximum, and its quiescent current is 2.1 mA typical and 5 mA maximum. The selection point is a through-hole, tab-mounted 8 A-class buck for industrial and automotive-accessory rails: the TO-220 body bolts to a heatsink, so sustained current is a thermal decision rather than a package-survival gamble. Selection advice: XLSEMI revises this document, and the current English revision is the governing basis for every figure on this page - qualify the offered lot against Rev 1.2 of the maker’s datasheet rather than any earlier edition circulating under the same code.
