These bits, along with the highest switching frequency limit, determine the threshold value for
enabling burst mode operation. For information about how to set this value, see the Light Load
Operation (Burst Mode) section. During burst mode, the PWM frequency is the maximum
frequency limit set in Register 0x46.
