XL2596S-5.0E1

XL2596S-5.0E1 is the TO-263-5L ordering code for the XLSEMI XL2596 fixed 5 V step-down converter, decoded in the ordering information of the current XLSEMI datasheet (Rev 2.1): S is the TO263-5L package, 5.0 is the fixed 5 V output and E1 is the lead-free finish - and this code is the tube-packed variant, where the tape-and-reel variant carries a different code, XL2596S-5.0TRE1. It accepts a 4.5 V to 40 V input, holds its 5 V output between 4.8 V and 5.2 V over a 7 V to 40 V input and a 0.2 A to 3 A load, switches at 127 kHz to 173 kHz (150 kHz typical), limits switch current between 3.6 A and 6.9 A (4.8 A typical), draws quiescent current of 2 mA typical and 10 mA maximum with standby current of 80 µA typical and 200 µA maximum, and is characterised at 80 % typical efficiency at a 12 V input and 3 A load. The selection point is a documented 3 A-class 5 V rail from vehicle and industrial inputs, in a tab package that solders to copper pour for cooling. Selection advice: quote the packing in full - E1 is tube packing, and a TRE1 offer changes handling on the line even though the silicon and footprint are identical. Parameters verified against the XLSEMI XL2596 datasheet Rev 2.1 (ordering information and the 5.0 V electrical table).
