Tool/software:
Hi TI experts,
According to the datasheet of LMQ61460AFS (SNVSB70F – MAY 2019 – REVISED JUNE 2021), it will run in 'forced PWM mode' (fPWM) under both heavy and light load conditions. However when we test it under light load (<1A, PWM frequency is set to 400KHz with RT=33.2Kohm), its switching frequency will shift to below 190KHz. Is this expected behavior, or I have wrong understanding on fPWM mode?
Thanks,
