2.1 Enable (EN) Jumper
This jumper is used to enable the device. Connecting the EN pin to
ENABLE enables the part. Connecting the EN pin to DISABLE disables the
device.
2.2 Mode Selection Jumper
This jumper is used to choose between PWM and PFM/PWM modes of
operation. Setting the jumper across FIXED FREQ forces the device into
the low-noise fixed frequency pulse width modulation (PWM) mode. Setting
the jumper across PWR SAVE enables the power save mode where the
device enters a pulse frequency modulation mode (PFM) at light to medium
load currents, which reduces quiescent current and switching frequency to
a minimum to achieve highest efficiency over the entire load current range.
