TPS26600PWPR from Texas Instruments, in a HTSSOP-16-EP. 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	IN	power_in	Power input and supply voltage of the device. Operating range 4.2 V to 60 V, absolute max 62 V. Pins 1 and 2 are internally connected and should be tied together.
2	IN	power_in	Power input and supply voltage of the device. Second IN pin (tie to pin 1).
3	UVLO	input	Input for setting the programmable undervoltage lockout threshold. An undervoltage event turns off the internal FET and asserts FLT. Connect UVLO to RTN to select the internal default threshold.
4	NC	unconnected	No connect.
5	OVP	input	Input for setting the programmable overvoltage protection threshold (TPS26600/1). An overvoltage event turns off the internal FET and asserts FLT. Connect OVP to RTN to select the internal default threshold; for the TPS26602 clamp variant, connect OVP to RTN externally.
6	MODE	input	Mode selection pin for overload fault response (auto-retry / latch-off / circuit-breaker). See Device Functional Modes.
7	SHDN	input	Active-low shutdown pin. Pulling SHDN low puts the device into low-power shutdown mode. Cycling SHDN resets a device that has latched off due to a fault.
8	RTN	passive	Reference for the device internal control circuits.
9	GND	power_in	Connect GND to system ground.
10	IMON	output	Analog current monitor output. Sources a scaled-down ratio (accuracy ±8.5%) of current through the internal FET. A resistor from this pin to RTN converts the current to a proportional voltage. Leave floating if unused.
11	ILIM	bidirectional	A resistor from this pin to RTN sets the overload and short-circuit current limit (0.1 A to 2.23 A, RILIM ≥ 5.36 kΩ for max 2.35 A).
12	dVdT	bidirectional	A capacitor from this pin to RTN sets the output voltage slew rate. See Hot Plug-In and In-Rush Current Control.
13	NC	unconnected	No connect.
14	FLT	output	Active-low fault event indicator. Open-drain output; leave floating if unused.
15	OUT	power_out	Power output of the device. Pins 15 and 16 are internally connected and should be tied together.
16	OUT	power_out	Power output of the device. Second OUT pin (tie to pin 15).
PAD	PowerPAD	passive	PowerPAD must be connected to the RTN plane on PCB using multiple vias for enhanced thermal performance. Do not use PowerPAD as the only electrical connection to RTN.
