TPS92201ADRVR from Texas Instruments, in a WSON-6-EP(2x2). 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 | PWM | input | PWM dimming input that sets LED output current from the PWM duty cycle (1% to 100%, 20 kHz to 200 kHz), with an absolute maximum of 6 V and a recommended range of -0.1 V to 6 V. |
| 2 | EN | input | Device enable input: logic high enables the device and logic low disables it into shutdown; it must be terminated and must not float, with an absolute maximum of 6 V. |
| 3 | VIN | power_in | Power supply input operating from 2.5 V to 5.5 V, with an absolute maximum of 6 V. |
| 4 | SW | power_out | Switch pin connecting the internal FET switch to the inductor terminal, rated -0.3 V to VIN + 0.3 V DC and -3 V to 9 V for 10 ns transients. |
| 5 | GND | power_in | Power ground; the input and output capacitor low sides must be connected to it to avoid ground potential shift. |
| 6 | FB | input | Feedback pin for the internal control loop; an external resistor from FB to GND sets the output current using the 100 mV typical reference (ILED = VFB / RSENSE), with an absolute maximum of 5.5 V. |
| 7 | EP | passive | Exposed thermal pad that must be soldered to the printed circuit board for thermal and mechanical performance. |
