TPS62293DRVR 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	SW	output	Switch pin connected to the internal MOSFET switches; connect the external inductor between this pin and the output capacitor.
2	MODE	input	A high level forces fixed-frequency PWM mode, and a low level enables power save mode with automatic transition from PFM mode to fixed-frequency PWM mode.
3	FB	input	Feedback pin for the internal regulation loop; connect the external resistor divider here, or connect it directly to the output capacitor for the fixed output voltage option.
4	EN	input	Enable pin; pulling it low forces shutdown mode and pulling it high enables the device, and this pin must be terminated.
5	VIN	power_in	Input voltage supply pin; the recommended supply voltage range is 2.3 V to 6 V.
6	GND	power_in	Ground supply pin.
7	EP	passive	Exposed pad (from the footprint; not named in the datasheet pin table).
