FB 7 I Feedback regulation point for the positive output voltage rail
FBG 6 I Feedback regulation point for the negative output voltage rail
GND 5 – Analog ground
L1 15 I/O Inductor terminal
16
L2 13 I/O Inductor terminal
14
OUTN 2 O Negative output
3
OUTP 9 O Positive output
10
PGND 11 – Power ground
12
VAUX 4 I/O Reference voltage output. This pin requires a 100-nF capacitor for stability.
VIN 1 I Input supply
