FUNCTIONAL DEVICE OPERATION
OPERATING MODES
BUCK SWITCHERS
pins, by direct state machine influence, or by load current magnitude when so configured. Available modes include PWM with
No Pulse Skipping (PWM), PWM with Pulse Skipping (PWMPS), Pulse Frequency Mode (PFM), and Off. The transition between
the two modes PWMPS and PFM can occur automatically, based on the load current. Therefore, no specific control is required
to put the switchers in a Low Power mode. When the buck switchers are not configured in the Auto mode, power savings may
be achieved by disabling switchers when not needed, or running them in PFM mode if loading conditions are light enough.
adaptive mode control (Auto). Additionally, provisions are made for maintaining PFM operation in USEROFF and MEMHOLD
modes to support state retention for faster startup from the low power Off modes for Warm Start or Warm Boot.

For regulators with internal pass devices and general outputs, the previous table can be simplified.
Operational modes of the Buck switchers can be controlled by direct SPI programming, altered by the state of the STANDBY
SW1, SW2, SW3, and SW4 can be configured for mode switching with STANDBY or autonomously based on load current with
