Description

Lx1

Switching node of the step-up converter

PGND

Power ground pin

VMID

Step-up converter output voltage (4.6V)

Not internally connected

AGND

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

VREF

Voltage reference output. 1µF bypass capacitor must be connected

between this pin and AGND

SWIRE

Negative voltage setting pin

Enable control pin. ON = VINA. When pulled low it puts the device in

shutdown mode

VO2

Inverting converter output voltage (Default - 4.9V)

Lx2

Switching node of the inverting converter

VIN A

Analogic input supply voltage

ViN P

Power input supply voltage

Exposed

pad

Internally connected to AGND. Exposed pad must be connected to AGND

and PGND in the PCB layout in order to guarantee proper operation of the

device
