TPS92201ADRVR

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

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.
