CC1108ST from Cross chip, in a SOT-23-5. 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 | VFB | input | LED drive current setting terminal. Connect an external resistor RFB between this pin and GND to program the constant output current: ILED = VFB / RFB, with VFB typically 150 mV (144-156 mV). Absolute max voltage -0.3 V to 5.5 V. |
| 2 | GND | power_in | Ground reference for the device. RFB feedback resistor returns to this pin. |
| 3 | DIM | input | PWM dimming control input with built-in 50 kΩ pull-up resistor to internal 5 V rail; may be left floating if dimming is not required (chip outputs maximum current). Logic levels: VIH >= 2.5 V, VIL <= 0.4 V. Absolute max voltage -0.3 V to 5.5 V. |
| 4 | VCC | power_in | Power supply input, 2.5 V to 24 V operating range (absolute max -30 V to 28 V). Features reverse-connection protection, with reverse leakage current below 10 uA at VCC = -30 V. For VCC >= 12 V direct-supply applications, a 1 kΩ series resistor is recommended to suppress hot-swap transients. |
| 5 | DRV | output | LED drive sink current output. Connects to the cathode of the LED string; sinks up to 200 mA continuous with a saturation drop of only ~175 mV. Absolute max voltage -0.3 V to 32 V. Leakage current below 1 uA when disabled. |
