# TPS92201DRVR

**Texas Instruments** · LED Drivers · WSON-6-EP(2x2)

TPS92201DRVR 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 input that adjusts LED output current according to the PWM duty cycle; the datasheet specifies a PWM frequency of 20 kHz to 200 kHz, a duty cycle of 1% to 100%, and a VPWM 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 be left floating, with VEN limited to -0.1 V to 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 on VIN. |
| 4 | SW | passive | Switch pin connecting the internal FET switch and the inductor terminal; DC limit is -0.3 V to VIN + 0.3 V and 10 ns AC transients are limited to -3 V to 9 V. |
| 5 | GND | power_in | Power ground pin. |
| 6 | FB | input | Feedback pin of the internal control loop; an external resistor from FB to GND sets the output current (ILED = VFB / RSENSE, with VFB typically 100 mV), and FB is rated -0.3 V to 5.5 V. |
| 7 | EPAD (thermal pad) | passive | Exposed thermal pad that must be soldered to the printed circuit board for thermal and mechanical performance; the datasheet does not state an electrical connection for it. |
