TPS62A02DRLR from Texas Instruments, in a SOT-563. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	GND	power_in	Ground pin. Common return for the input capacitor, output capacitor, and internal control circuitry.
2	SW	output	Switch node connected to the internal high-side and low-side FETs and the inductor terminal. Connect the output filter inductor (typ. 1.0 µH) between SW and VOUT. Absolute max -0.3 V to VIN+0.3 V DC; -3 V to 10 V transient <10 ns.
3	VIN	power_in	Input supply voltage pin, 2.5 V to 5.5 V. Place the input capacitor as close as possible between VIN and GND. Absolute max 6.5 V.
4	EN	input	Device enable logic input. Logic high (>1.2 V rising) enables the converter; logic low (<0.4 V falling) forces shutdown (≤2 µA IQ). Do not leave floating. Absolute max 6.5 V.
5	FB	input	Feedback pin for the internal control loop. Connect this pin to the center tap of an external resistor divider from VOUT to set the output voltage. Internal reference VFB = 600 mV (±1% at 0-125°C).
6	PG	output	Power-good open-drain output pin. Requires an external pullup resistor tied to a rail no higher than 5.5 V (do NOT tie to a rail higher than 5.5 V even if VIN is higher). Asserts high when FB is within ~96% of nominal; leave open or tie to GND if unused.
