5.1 Application-Based Configuration Settings
In the TPS6594-Q1 data sheet, there are seven application-based configurations for each BUCK to operate
within. The following list includes the different configurations available:
• 2.2 MHz Single Phase for DDR Termination
• 4.4 MHz VOUT Less than 1.9 V, Multiphase or High COUT Single Phase
• 4.4 MHz VOUT Less than 1.9 V, Low COUT, Single Phase Only
• 4.4 MHz VOUT Greater than 1.7 V, Single Phase Only
• 2.2 MHz VOUT Less than 1.9 V Multiphase or Single Phase
• 2.2 MHz Full VOUT Range and VIN Greater than 4.5 V, Single Phase Only
• 2.2 MHz Full VOUT and Full VIN Range, Single Phase Only
The seven configurations also have optimal output inductance values that optimize the performance of each
buck under these various conditions.
shows the default configurations for the BUCKs. These settings
cannot be changed after device startup.
