Description
High-Side Gate Drive Boost Input. BS supplies the drive for the high-side N-Channel MOSFET
switch. Connect a 0.01
μ
F 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 23V 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 the exposed pad to Pin 4).
Feedback Input. FB senses the output voltage and regulates it. Drive FB with a resistive
voltage divider connected to it 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. 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; low to turn it off. Attach to IN with a 100k
pull up 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 0.1
μ
F capacitor sets the soft-start period to 15ms. To disable the
soft-start feature, leave SS unconnected.
