Pin Layout

PIN Layout	PIN	Name	Type	PIN Function
	1	dV/dT	Analog I/O	A capacitor from this pin to GND sets the output turn on slew rate. Leave this pin Floating for the fastest turn on slew rate. (See Switching Characteristics).
	2	EN/UVLO	Analog input	Active high enables for the Group A, Group C variants. A resistor divider can be used to adjust the under-voltage lockout threshold. Do not leave floating.
		ENB/OVLO		Active low enables for the Group B variants. A resistor divider can be used to adjust the over-voltage lockout threshold. Do not leave floating.
	3,4	VIN	Power	Power input.
	5	OUT	Power	Power output.
	6	FLTB	Digital output	Group A+ Group B: Fault event indicator which is pulled low when a fault is detected.
		QOD		Group C: Quick Output Discharge Pin, when tied to OUT directly or through external Resistor
	7	ILM	Analog I/O	This is a dual function pin used to limit and monitor the output current. An external resistor from this pin to GND sets the output current limit. The pin voltage can also be used to monitor the output load current. Do not leave floating.
	8	GND	Ground	Ground.
	Thermal Pad	GND	Ground	The exposed pad is used primarily for heat dissipation and must be connected to GND.
