BUCK3-5 Mode | Auto | Auto | Auto | Auto | Forced PWM | Forced PWM |
Using OTP parts TPS650945 & TPS650947 with Forced PWM mode for Bucks 3-5 is strongly recommended to avoid abnormal frequency switching and minimize noise at light loads . Voltage undershoot or overshoot may be observed when operating with light load in Auto mode, and can lead to shutdown.
