IW3627-00 from Dialog Semiconductor, 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	VCC	power_in	Power supply to control logic and MOSFET drive. DC supply voltage range -0.3 to 18.0V, ICC = 20mA max.
2	FB/FMAX	input	Multi-function analog input. Used to configure maximum switching frequency (FMAX) and to enable/disable over-load protection (OLP) at the beginning of start-up. Also provides output voltage sense for primary regulation during normal operation. Range -0.7 to 4.0V, IFB/OTP <= 10mA.
3	VIN	input	Multi-function analog input. Used to control active start-up device and sense line voltage for input under-voltage protection. Range -0.3 to 18.0V.
4	CS/FMIN	input	Multi-function analog input. Used to configure minimum switching frequency (FMIN) at the beginning of start-up. Also provides primary current sense for cycle-by-cycle peak current control and limit during normal operation. Range -0.3 to 4.0V.
5	GND	power_in	Ground reference for the IC.
6	OUTPUT	output	Gate drive output for external MOSFET switch. Range -0.3 to 18.0V. Enhanced MOSFET driver supports output power up to 90W in SOT-23 package.
