TPS62261DRVR

Texas Instruments · DC-DC Converters · WSON-6(2x2)

TPS62261DRVR from Texas Instruments, in a WSON-6(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 SW output The switch pin connects to the internal MOSFET switches, and the external inductor is connected between this terminal and the output capacitor.
2 MODE input Pulling MODE high forces fixed-frequency PWM operation, while pulling it low enables power save mode with automatic transition from PFM to fixed-frequency PWM; this pin is only available in the WSON package option.
3 FB input Feedback pin for the internal regulation loop, where the external resistor divider connects for adjustable output or, for the fixed-output option, it connects directly to the output capacitor.
4 EN input Enable pin where pulling low forces the device into shutdown mode and pulling high enables the device, and this pin must be terminated.
5 VIN power_in VIN power supply pin, with a recommended supply voltage range of 2 V to 6 V and an absolute maximum input voltage of 7 V.
6 GND power_in GND supply pin.
7 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
