XL6019E1

XLSEMI · DC-DC Converters · TO-263-5

XL6019E1 from XLSEMI, in a TO-263-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground pin. Common return for input, output and internal circuitry.
2 EN input Enable pin. TTL-compatible: logic low shuts the converter down, logic high enables operation. Threshold typ. 1.4V (high) / 0.8V (low). Floating is treated as high. VEN range -0.3V to VIN.
3 SW output Power switch output. Drain of the internal N-channel power MOSFET; connect to the inductor/diode boost node. Absolute max VSW = 60V, internal SW overvoltage clamp typ. 60V. Also brought out on the metal tab.
4 VIN power_in Power supply input, 5V to 40V DC. Requires a bulk electrolytic capacitor between VIN and GND to suppress noise. Absolute max 45V.
5 FB input Output-voltage feedback sense pin. Internal reference is 1.25V; set VOUT with a resistor divider using VOUT = 1.25 × (1 + R2/R1).

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: XLSEMI datasheet (14 pp, sha256 a08dcab1375258c6, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
