SETTINGS FILES AND EEPROM
The ADP1046 communicates with the GUI software using the
I 2 C bus.
The register settings (having extension .46r) and the board
settings (having extension .46b) are two files that are associated
(ADP1046_I2SF_032011.46b)). The register settings file con-
tains information such as the overvoltage and overcurrent
limits, soft start timing, and PWM settings that govern the
functionality of the part. The ADP1046 stores all settings in
the EEPROM.
The EEPROM on the ADP1046 does not contain any infor-
mation about the board, such as current sense resistor, output
inductor, and capacitor values. This information is stored in a
board setup file (extension .46b) and is necessary for the GUI
to display the correct information in the Monitor window as
well as the Filter Settings window (not shown). The entire
status of the power supply, such as the ORFET and enable/disable
Evaluation Board User Guide
of the synchronous rectifiers, primary current, output voltage,
and output current, can thus be digitally monitored and
controlled using software only. Always make sure that the
correct board file is loaded for the board currently in use.
Each ADP1046 chip has trim registers for the temperature,
input current, output voltage, output current, and ACSNS.
These can be configured during production and are not overwrit-
ten whenever a new register settings file is loaded. This is done
to retain the trimming of all the ADCs for that corresponding
environmental and circuit condition (for example, component
tolerances and thermal drift). A guided wizard called the Auto
Trim can be used to trim the previously mentioned quantities
of the trim registers (for example, temperature, input current,
output voltage) so that the measurement value matches the values
displayed in the GUI, which allows ease of control through the
software. Click Voltage Settings or CS2 Settings in the Setup
window (see Figure 9) to access the Auto Trim wizard.
