XL7005A

XL7005A is the SOIC-8-EP (SOP8-EP) ordering code for the XLSEMI XL7005A high-voltage step-down converter, listed in the ordering information of the current XLSEMI datasheet (Rev 1.8) and packed 4000 pieces per reel. It accepts a 5 V to 80 V input, holds its feedback voltage between 1.225 V and 1.275 V (1.25 V typical), switches at 120 kHz to 180 kHz (150 kHz typical), shows a typical switch current limit of 0.5 A, draws quiescent current of 2.5 mA typical and 5 mA maximum with shutdown current of 85 µA typical and 200 µA maximum, reaches a maximum duty cycle of 90 %, and is characterised at 86 % typical efficiency at a 36 V input with a 15 V, 0.2 A output. The selection point is a half-ampere rail straight from high-voltage buses: e-bike and industrial auxiliary supplies, lighting drivers and appliance controls step 48 V-class inputs down without a pre-regulator stage. Selection advice: the 0.5 A figure is the switch current limit, not a guaranteed continuous output current - budget the load against the datasheet output-current curves for the actual input and output voltages, and use the exposed pad as the main thermal path.
