XL6019E1

XL6019E1 is the TO-263-5 ordering code for the XLSEMI XL6019 step-up (boost) converter, listed in the ordering information of the current XLSEMI datasheet; the E1 suffix designates the lead-free, RoHS-compliant product. It accepts an input from 5 V to 40 V, regulates against a feedback voltage of 1.213 V minimum, 1.25 V typical and 1.287 V maximum, switches at 144 kHz to 253 kHz (180 kHz typical), limits switch current at 5 A, shows an internal switch resistance of 110 mΩ typical and 120 mΩ maximum at 5 A, reaches a maximum duty cycle of 90 %, draws a shutdown current of 70 µA typical and 100 µA maximum and a quiescent current of 2.5 mA typical and 5 mA maximum, and reaches 93 % typical efficiency converting 12 V to 24 V. The selection point is a 5 A switch inside a power-tab package: 12 V to 24 V industrial rails, automotive accessory supplies and LED backlight boosts get the current headroom without an external MOSFET stage. Selection advice: XLSEMI publishes no lifecycle grading for this family, so qualify the code against the current datasheet revision at design-in; the TO-263 tab is the thermal path, and sustained high boost ratios need the copper area the datasheet application section assumes. Parameters verified against the XLSEMI XL6019 datasheet (ordering information and electrical characteristics).
