Figure 28. Average Current Mode Control
Power-save mode and synchronization
The PS/SYNC pin can be used to select different operation modes. Power Save Mode is used to improve
efficiency at light load. To enable Power-Save, PS/SYNC must be set low. If PS/SYNC is set low then Power
Save Mode is entered when the average inductor current gets lower then about 100mA. At this point the
converter operates with reduced switching frequency and with a minimum quiescent current to maintain high
efficiency.
During the Power Save Mode, the output voltage is monitored with a comparator by the threshold comp low and
comp high. When the device enters Power Save Mode, the converter stops operating and the output voltage
drops. The slope of the output voltage depends on the load and the value of output capacitance. As the output
voltage falls below the comp low threshold set to 2.5% typical above Vout, the device ramps up the output
voltage again, by starting operation using a programmed average inductor current higher than required by the
current load condition. Operation can last for one or several pulses. The converter continues these pulses until
the comp high threshold, set to typically 3.5% above Vout nominal, is reached and the average inductor current
gets lower than about 100mA. When the load increases above the minimum forced inductor current of about
100mA, the device will automatically switch to PWM mode.
The Power Save Mode can be disabled by programming the PS/SYNC high. Connecting a clock signal at
PS/SYNC forces the device to synchronize to the connected clock frequency.
Synchronization is done by a PLL to lower and higher frequencies compared to the internal clock. The PLL can
also tolerate missing clock pulses without the converter malfunctioning. The PS/SYNC input supports standard
logic thresholds.
