PRODUCTION DATA
The resistor to AGND for MSEL1 selects the (B1h) USER_DATA_01 (COMPENSATION_CONFIG) values to program the following voltage loop and current loop gains. For options other than the EEPROM code (MSEL1 shorted to AGND or MSEL1 to AGND resistor code 0), the current and voltage loop zero and pole frequencies are scaled with the programmed switching frequency.
Based on the design tool, for a switching frequency of 650kHz, the TPSM8S6B24S must use an ILOOP of 7 and a maximum voltage loop bandwidth of 29kHz (from design tool).
For this design, VLOOP = 8 is selected.
For ILOOP = 7, VLOOP = 8, Compensation Code 30 is selected and MSEL1 is terminated with resistor divider code 9 and resistor to ground code 14, selecting a top 38.3kΩ resistor and bottom 68.1kΩ resistor
