Function
Connect the output inductor to this pin. The switching node is
internally connected to the drain of both high- and low-side
MOSFETs.
Main power ground return pin. Connect to the output and
input capacitor return.
Connect to ground for PFM/PWM mode and optimized effi-
ciency throughout the load range. Connect to high for low
noise PWM Only operation under all operating conditions.
Connect to an external clock for synchronization (PWM Only).

Cwire input for pro-
grammable output voltages.
Feedback input pin. This pin is connected directly to the con-
verter output for programmable output.
Ground connection pin.
Input voltage for the converter.
Input voltage for the power switches.
Not connected.
Exposed paddle (bottom); connect to ground as closely as
possible to the device.
