CC1109 from Cross chip, in a SOT-89-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | DIM | input | PWM dimming input with internal pull-up, so floating DIM gives maximum output current; logic high requires at least 2.5V and logic low at most 0.4V, with absolute maximum -0.3V to 5.5V. |
| 2 | GND | power_in | Ground reference; the output current-setting resistor RFB is connected between VFB and this pin. |
| 3 | VFB | passive | Output current setting pin where RFB sets the LED current against a typical 150mV reference (144 to 156mV at VDRV=2V, RFB=5Ω), with absolute maximum -0.3V to 5.5V. |
| 4 | DRV | output | Output current sink pin that carries the LED current, with absolute maximum voltage -0.3V to 32V and continuous current rating of 600mA absolute maximum (200mA recommended continuous). |
| 5 | VCC | power_in | Supply pin with a 2.5V to 24V operating range, absolute range -30V to 28V, and reverse-connection protection limiting reverse current to 10uA. |
