Getting Started
The AS1363 Demoboard is designed to work with the AS1363 fixed output voltage version.
The AS1363 fixed Vout version is available with 1.5V, 1.8V, 3.0V, 3.3V and 4.5V.
The AS1363-AD Demoboard is designed to work with the AS1363 adjustable output voltage version.
The AS1363-AD adjustable Vout version has a valid Vout range from 1.2V to 5.3V. This Vout is adjustable via the
resistor divider R1/R2. A value for R2 in the range of 25kΩ to 100kΩ should be sufficient.
To use the factory preset Vout of 2.5V connect SET directly to GND (R1 = open; R2 = 0Ω).
