HX3001-AFC

HEXIN · DC-DC Converters · SOT-23-6

HX3001-AFC from HEXIN, in a SOT-23-6. 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 SW output Switch pin. Connect the boost inductor between SW and VIN. Internal NMOS (0.35Ω) and synchronous PMOS (0.45Ω) switch this node; keep PCB traces short and wide to reduce EMI and voltage overshoot. Absolute max -0.3V to 6.6V.
2 GND power_in Signal and power ground. Provide a short, direct PCB path between GND and the negative side of the output capacitor(s).
3 FB input Feedback input to the gm error amplifier. Connect the resistor divider tap here; output voltage is set by VOUT = 1.212V × [1 + (R1/R2)]. Reference feedback voltage is typ. 1.212V (1.165-1.241V); input bias current is ~1nA.
4 EN input Logic-controlled shutdown input, active-high enable. VENH ≥ 1V enables normal 1.4MHz operation; VENL ≤ 0.5V shuts the device down (IQ ≈ 2µA). Absolute max -0.3V to 6.6V; input leakage ≤ 1µA at 5.5V.
5 VOUT power_out Regulated output voltage pin (adjustable 2.5V to 5V). Once VOUT exceeds VIN, the device draws its bias from VOUT. Keep the trace from VOUT to the output filter capacitor(s) short and wide. Absolute max -0.3V to 6.6V.
6 VIN power_in Battery/input supply pin. Provides start-up bias; HX3001-AFC starts from 1V (input range 1V-4.4V, absolute max -0.3V to 5V). Once VOUT exceeds VIN, operation is largely independent of VIN.

Provenance

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

  • Datasheet: HEXIN datasheet (9 pp, sha256 26f26237bb3ce43a, retrieved 2026-08-17, tier: lcsc)
  • 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).
