PIN CONFIGURATION
PIN DESCRIPTIONS
PIN NAME
DESCRIPTION
1
HSB
High-Side Bias Input. This pin acts as the positive rail for the high-side switch's gate
driver. Connect a 10nF or greater capacitor between HSB and SW pins.
2
IN
Input Supply. Bypass this pin to GND with a low ESR capacitor. Drive IN with a 4.5V to
18V power source. See Input Capacitor in the Application Information section.
3
SW
Switch Output. Connect this pin to the switching end of the external inductor. Note that
a capacitor is required from SW to HSB to power the high-side switch.
4
GND
Ground.
Feedback Input. FB senses the output voltage to regulate that voltage. Drive FB with a
5 FB resistive voltage divider from the output voltage. The feedback threshold is 0.923V.
See Setting the Output Voltage.
6
COMP
Compensation Node. COMP is used to compensate the regulation control loop. See
Compensation Components.
Enable Input. When higher than 2.5V, this pin turns the IC on. When lower than 2.3V,
7 EN this pin turns IC off. When left unconnected, EN is pulled up to logic HIGH with a 2µA
pull-up current. EN is a digital input that turns the regulator on or off.
8 N/C Not connected.
