1.3 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.
