TP8204HS6-B from TECH PUBLIC, in a SOT-23-6. 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	Device ground return. Connect to system ground plane; carries switching return currents.
2	LX	output	Switching node. Internal high-side and low-side MOSFETs connect here; drive the external inductor from LX. Swings between GND and VIN at 500kHz.
3	IN	power_in	Power supply input. 4.5V to 17V input voltage range. Bypass with a low-ESR ceramic capacitor (e.g. 22uF) close to the pin.
4	FB	input	Adjustable-version feedback input. Connect FB to the center point of the external resistor divider. Regulated to 0.8V typical (0.780V min / 0.820V max).
5	EN	input	Enable input. Drive logic-high (Vih >= 1.5V) to enable the IC; drive logic-low (Vil <= 0.5V) to disable the IC and enter micro-power shutdown mode (~1uA). Absolute max 6V.
6	BS	passive	Bootstrap pin for the high-side MOSFET gate driver. Connect a capacitor (typ. 1uF) between LX and BS to form a floating supply across the high-side switch driver.
