Auto-skip Eco-mode or Forced Continuous Conduction Mode (FCCM) can be selected using the SS_SEL pin (pin 3). Connect the SS_SEL pin to PGND to select Auto-skip Eco-mode or to the PWRGD pin to select FCCM.
In Auto-skip Eco-mode, the LMZ31530 automatically reduces the switching frequency at light load conditions to maintain high efficiency. In FCCM, the controller keeps continuous conduction mode in light load condition and the switching frequency is kept almost constant over the entire load range. Transient performance is best in FCCM.
