PIN CONFIGURATION
PIN DESCRIPTIONS
PIN NAME
DESCRIPTION
1
CS1
The output current of VOUT1 is sensed by this pin. When the voltage on this pin reaches
116mV for 750µs, the IC shuts down for 2.5 seconds before initiating a restartup.
2 SW Switch Output. Connect this pin to the switching end of the external inductor.
3
HSB
High Side Bias. This pin acts as the positive rail for the high-side switch’s gate driver.
Connect a 22nF-100nF capacitor between HSB and SW pins.
4
GND
Ground.
5
COMP
Compensation Node. COMP is used to compensate the voltage regulation loop.
Feedback Input. FB senses the output voltage to regulate that voltage. Drive FB with a
6 FB resistive voltage divider from the output voltage. The feedback threshold is 0.808V.
See Setting the Output Voltage.
7 IN Input Supply. Bypass this pin to GND with a 10µF or greater low ESR capacitor.
8
CS2
The output current of VOUT2 is sensed by this pin. When the voltage on this pin reaches
116mV for 750µs, the IC shuts down for 2.5 seconds and then restarts.
Exposed Pad Exposed Pad. Connect this pad to thick copper plane via copper vias.
