TPS61166DSKR from Texas Instruments, in a DFN-10-EP(2.5x2.5). 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 | GND | power_in | Ground of the IC. |
| 2 | VIN | power_in | IC supply voltage input, specified for 2.5 V to 6 V. |
| 3 | VBAT | power_in | Battery supply voltage input for the power stage, specified for 4.5 V to 10 V; it can be tied to VIN for a single-cell Li-ion battery. |
| 4 | NC | unconnected | No connect pin; connecting it to ground is recommended, or it can float. |
| 5 | EN | input | Enable pin (HIGH = enable) with VENH of 1.2 V minimum and VENL of 0.3 V maximum; pulling it low for 1 ms shuts the IC down, drawing less than 1 µA. |
| 6 | PWM | input | LED on/off control; a PWM signal from 60 Hz to 40 kHz applied to this pin sets LED brightness, with logic levels as specified for EN/PWM (VENH 1.2 V minimum, VENL 0.3 V maximum). |
| 7 | FB | input | Cathode of the LED connects to this pin; the feedback voltage is regulated at 0.2 V (194 mV to 206 mV) and an external resistor programs the LED current. |
| 8 | OUT | output | Output of the isolation switch, which sits between this pin and VO; the LED anode connects to this pin. |
| 9 | SW | input | Switching node of the IC where the PWM switching operates; absolute maximum voltage is 20 V with respect to ground. |
| 10 | VO | output | Boost converter output; when VO exceeds the 18 V (typ) overvoltage protection threshold the power switch turns off until VO drops below the OVP hysteresis. |
| 11 | Thermal Pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
