Description

1

Boost converter switching node.

PGND

2

Power ground pin.

3

Boost converter output voltage.

FD

4

Fast discharge control pin. When pulled LOW the fast discharge after

shutdown is active. When pulled HIGH the fast discharge is OFF.

AGND

5

Signal ground pin. This pin must be connected to the power ground

layer.

6

Voltage reference output. 1µF bypass capacitor must be connected

between this pin and AGND.

7

Negative voltage setting pin.

EN

8

Enable control pin. high = converter on; low = converter in shutdown

mode.

9

Inverting converter output voltage.

10

Inverting converter switching node.

11

Analogic input supply voltage.

12

Power input supply voltage.

Exposed

Pad

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.
