Hichips · LED Drivers · SOT-89-5

X10S from Hichips, in a SOT-89-5. 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 DIM input PWM dimming input. Logic-high (>0.7VDD) enables output; logic-low (<0.3VDD) disables output. Supports pulses as narrow as 60ns for high-resolution dimming. Internally pulled up (~100uA), defaults high when floating. Abs-max -0.3 to 6.0V.
2 GND power_in Chip ground reference. Package bottom pad is also chip ground; PCB layout should provide copper flooding for heat dissipation.
3 REXT passive Output current programming pin. Connect a resistor from REXT to GND; output current Iout(mA) = 1860 / REXT(kΩ). Abs-max -0.3 to 6V.
4 IOUT output Constant-current LED drive output (sink). Programmable 20-500mA via REXT, ±3% accuracy. Withstands up to 46V. Constant-current knee ~0.4V at 150mA, ~0.7V at 300mA, ~0.88V at 450mA.
5 VCC power_in Chip supply pin, internally clamped to 5.2V (typ, 4.7-6.1V) by an on-chip 5V shunt regulator. Fed from VIN (5-46V) through an external dropping resistor R0. IDD ~1mA typ; clamp current up to 25mA. Requires ≥1.0uF bypass capacitor placed close to the pin.

Provenance

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

  • Datasheet: Hichips datasheet (7 pp, sha256 ba019b52ba56c751, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • 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).
