Pin Descriptions

1.3.1

VFET

Input to the internal voltage regulator.

1.3.2

VCC

Digital supply voltage. Normally connected to VREG.

1.3.3

VREG

Output from the internal voltage regulator.

1.3.4

CF1P/CF1N/CF2P/CF2N

CF1P/CF1N/CF2P/CF2N are the connection pins for connecting external fly capacitors to the

step-up regulator.

1.3.5

VREF

Internal Voltage Reference for external decoupling.

1.3.6

VREFGND

Ground for decoupling of Internal Voltage Reference. Do not connect to GND or SGND on PCB.
