RYCHIP · LED Drivers · SOT-23-6
RY7117AT6 from RYCHIP, in a SOT-23-6. 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 | FB | input | Output current feedback pin, where the output current is IOUT = 0.1V/RS1 and the feedback reference is 94-106 mV (100 mV typical) at VDIM = 1.2V. |
| 2 | DIM | input | Dimming signal input with a dimming voltage range of 0.65V-1.2V that must not be left floating; the device is enabled above 1.2V and shut down below 0.55V. |
| 3 | GND | power_in | Ground pin. |
| 4 | IN | power_in | Input supply pin with an input voltage range of 4.5V to 16V, to be decoupled to GND with a 10μF ceramic capacitor. |
| 5 | SW | output | Switching pin; the absolute maximum SW voltage is -0.3V to 20V (-5V to 20V for a 10ns transient). |
| 6 | BS | power_in | Bootstrap pin supplying the top-side gate driver, to be decoupled to SW with a 0.1μF ceramic capacitor. |
