Top View Description
High Side Gate Drive Boost Input. A 10nF or greater capacitor must be connected from
this pin to SW. It can boost the gate drive to fully turn on the internal high side NMOS.
Power Supply Input Pin. Drive 4.8V to 40V voltage to this pin to power on this chip.
Connecting a 10uF ceramic bypass capacitor between VIN and GND to eliminate noise.
Power Switching Output. It is the output pin that internal high side NMOS switching to
supply power.
Ground Pin. Connecting EP(exposed pad) to Pin 4.
Voltage Feedback Input Pin. Connecting FB and VOUT with a resistive voltage divider.
This IC senses feedback voltage via FB and regulate it at 0.935V.
Compensation Pin. This pin is used to compensate the regulation control loop. Connect
a series RC network from COMP pin to GND.
Enable Input Pin. This pin provides a digital control to turn the converter on or off.
Connect to VIN with a 100Kresistor for self-startup.
Soft-Start Input Pin. This pin controls the soft-start period. Connect a capacitor from SS
to GND to set the soft start period.
