Description
High-Side Gate Drive Boost Input. BS supplies the drive for the
high-side N-Channel MOSFET switch. Connect a 0.01μF or greater
capacitor from SW to BS to power the high side switch.
Power Input. IN supplies the power to the IC, as well as the step-down
converter switches. Drive IN with a 4.75V to 18V power source. Bypass
IN to GND with a suitably large capacitor to eliminate noise on the input
to the IC. See Input Capacitor.
Power Switching Output. SW is the switching node that supplies power
to the output. Connect the output LC filter from SW to the output load.
Note that a capacitor is required from SW to BS to power the high-side
switch.
Ground (Connect Exposed Pad to Pin 4).
Feedback Input. FB senses the output voltage to regulate that voltage.
Drive FB with a resistive voltage divider from the output voltage. The
feedback threshold is 0.925V. See Setting the Output Voltage.
Compensation Node. COMP is used to compensate the regulation
control loop. Connect a series RC network from COMP to GND to
compensate the regulation control loop. In some cases, an additional
capacitor from COMP to GND is required. See Compensation
Components.
Enable Input. EN is a digital input that turns the regulator on or off.
Drive EN high to turn on the regulator, drive it low to turn it off. Pull up
with 100kΩ resistor for automatic startup.
Soft-Start Control Input. SS controls the soft-start period. Connect a
capacitor from SS to GND to set the soft-start period. A 0.1μF capacitor
sets the soft-start period to 15ms. To disable the soft-start feature,
leave SS unconnected.
