Table 4-1 Pin Functions

PIN		TYPE	DESCRIPTION
NO.	NAME	TYPE	DESCRIPTION
1	HVIN	Analog input	High-voltage input
2	INN	Analog input	Ground sense pin and inverting analog input to the modulator. Connect to GND1.
3, 7, 8, 12, 13, 15	NC	N/A	No internal connection. The pin can be connected to any potential or left floating.
4	SNSP	Analog input	Sense voltage pin and non-inverting analog input to the modulator. Connect to an external filter capacitor or leave floating.
5	VDD1	High-side power	Analog (high-side) power supply⁽¹⁾
6	GND1	High-side ground	High-side ground
9	GND2	Low-side ground	Low-side ground
10	OUTN	Analog output	Inverting analog output
11	OUTP	Analog input	Noninverting analog output
14	VDD2	Low-side power	Low-side power supply⁽¹⁾
