SYNC/MODE
Function
Feedback Analog Input. Connect to the output at the output filter capacitor (Figure 1)
Output Voltage Control Inputs. Set the output voltage using these digital inputs (see Table
1). The output defaults to 1.5V if these pins are unconnected.
Synchronization Input. Use this digital input for frequency synchronization or modulation
control. Set:
SYNC/MODE = high for low-noise 600kHz PWM mode
SYNC/MODE = low for low-current PFM mode
SYNC/MODE = 500kHz - 1MHz external clock for synchronization to an external clock in
PWM mode. See
Synchronization and Operating Modes
in the
Device Information
section.
Enable Input. For shutdown, set low to SGND.(See
Shutdown Mode
in the
Device
Information
section.)
