pad
Boost converter switching node
Power ground pin
Boost converter output voltage
Fast discharge control pin. When pulled LOW, the fast discharge after
shutdown is active. When pulled HIGH, the fast discharge is OFF
Signal ground pin. This pin must be connected to the power ground layer
Voltage reference output. 1 µF bypass capacitor must be connected
between this pin and AGND
Negative voltage setting pin
Enable control pin. High = converter on; Low = converter in shutdown
mode
Inverting converter output voltage
Inverting converter switching node
