40 / 50

•

Read current OTP configuration (write operation is not possible). To display the

accurate data, the device needs to operate in Test mode.

SPI/I2C:

•

Configure the device to work with FIN input

•

Select the signal to apply on FOUT pin

•

Play with manual frequencies and spread spectrum

8.4.3 Regulators

The regulator has two main areas:

•

Low voltage (LV) regulators configuration

•

VPRE compensation network calculation

Each regulator can either be enabled or disabled by SPI/I2C. The thermal shutdown

behavior can be configured to either shutdown the regulator, or shutdown the regulator

and transition to deep fail-safe. The write button applies to the entire table. The

VPRE compensation network calculator helps to define the value for VPRE external

compensation network.

Figure 33. Regulators

8.4.4 Measurements

This tab enables two features:

•

Read any of the AMUX signals over time

•

Display regulator voltage summary
