2.2.4 Switching Frequency Setting

The switching frequency is set to a default of 2.25 MHz. By changing the values of R101 and R102, the default switching frequency can be changed. If R101 and R102 are changed the same change must be done with R201, R301 (same value as R101) and R202, R302 (same value as R102). For more details, see the TPS62876-Q1 Automotive, Low Input Voltage, 25-A, Stackable, Synchronous Buck Converter data sheet.
