TPS40192DRCR from Texas Instruments, in a VSON-10-EP(3x3). 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	ENABLE	input	Logic-level enable input which starts or stops the controller from an external user command. A high level turns the controller on. A weak internal pullup holds this pin high so the pin may be left floating if unused.
2	FB	input	Inverting input to the error amplifier. In normal operation the voltage on this pin equals the internal reference voltage (591 mV typical).
3	COMP	output	Output of the error amplifier. Used for loop compensation and also sets the short-circuit comparator threshold via an external resistor to GND.
4	VDD	power_in	Power input to the controller. Recommended operating range 4.5 V to 18 V; absolute max 20 V.
5	PGD	output	Open-drain power-good output. Requires an external pull-up resistor.
6	BP5	power_out	Output bypass for the internal 5 V regulator (5.1 V to 5.5 V). Connect a capacitor of at least 1 uF (up to 4.7 uF) from this pin to GND. External load plus MOSFET gate-drive requirements must not exceed 50 mA. Turned off when ENABLE is pulled low.
7	LDRV	output	Gate-drive output to the low-side (rectifier) N-channel MOSFET.
8	BOOT	input	Gate-drive supply for the high-side N-channel MOSFET. A 100 nF typical bootstrap capacitor must be connected between this pin and SW. Absolute max 30 V referenced to GND; 6 V referenced to SW.
9	SW	input	Switch-node sense input for the adaptive anti-cross-conduction circuitry. Also serves as the common (return) connection for the flying high-side MOSFET driver. Absolute max -5 V to 25 V.
10	HDRV	output	Bootstrapped gate-drive output for the high-side N-channel MOSFET.
11	GND	power_in	Thermal pad; common reference for the device. Connect to system GND. Required for proper electrical operation and heat dissipation.
