JAJSPL9 july 2023 TPS631012 , TPS631013
PRODMIX
The TPS631012 and TPS631013 have two modes of PFM and FPWM. During PFM mode operation, the devices feature a power save mode to maintain the highest efficiency over the full operating output current range. In PFM mode the devices automatically change the converter operation from CCM to pulse frequency modulation. During FPWM mode, the devices use PWM for all operating conditions regardless of the output current to achieve minimum output ripple.
The PFM/FPWM mode selection is controlled by the FPWM bit in Register CONTROL2:
