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.
