DX12410-L from Dersem, in a ESOP-8. 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, internally pulled up with about 100uA and defaulting high when floating; output turns off when held low and the chip enters sleep mode after low for more than 120ms, with an absolute maximum rating of -0.3 to 6.0V. |
| 2 | NC | unconnected | No connection; the datasheet specifies this pin as floating (悬空). |
| 3 | CS1 | passive | Output current sense pin 1; output current is set by the external sense resistor as IOUT = 0.137 / RCS, and the CS port is rated -0.3 to 6V. |
| 4 | CS2 | passive | Output current sense pin 2; output current is set by the external sense resistor as IOUT = 0.137 / RCS, and the CS port is rated -0.3 to 6V. |
| 5 | VDDO | power_out | 5V supply pin that can power an external PWM control chip when needed (DX1240 and DX12410 only); the datasheet lists VDDO as 5.6V and the VDD port rating as -0.3 to 6V. |
| 6 | DRAIN | output | LED driver pin connected to the internal NMOS drain; for DX12410 the output (VIOUT) withstand voltage is -0.3 to 100V. |
| 7 | VIN | power_in | Supply input with an operating range of 3.0 to 40V per the electrical table (2.5V minimum operation stated in the text) and an absolute maximum rating of -0.3 to 46V; a clamp to GND is recommended above 36V. |
| 8 | GND | power_in | Chip ground. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
