Exposed
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. 1µF 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.
Analogic input supply voltage.
Power input supply voltage.
Internally connected to AGND. Exposed pad must be connected to
ground layers in the PCB layout in order to guarantee proper operation
of the device.
