Pin Descriptions
1.3.1
VFET
Input to the internal voltage regulator.
1.3.2
1.3.3
1.3.4
VCC
Digital supply voltage. Normally connected to VREG.
Output from the internal voltage regulator.
VREG
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
1.3.6
VREF
Internal Voltage Reference for external decoupling.
VREFGND
Ground for decoupling of Internal Voltage Reference. Do not connect to GND or SGND on PCB.
