FUNCTION
Ground. Connect both GND pins together.
Select Input. Control input to select from either V IN_ or V AUX_ for both outputs. Pull SEL high for
power from IN source, low for power from AUX source.
Auxiliary Input. Connect both AUX pins together and bypass with a 0.1μF capacitor to ground.
Load conditions may require additional bulk capacitance to maintain AUX voltage regulation.
Power Input. Connect both IN pins together and bypass with a 0.1μF capacitor to GND. Load
conditions may require additional bulk capacitance to maintain the IN voltage regulation.
Control Input. A logic low at ON turns on the device. A logic high shuts off both outputs and all
power to internal circuits. Driving ON higher than IN does not cause damage.
Fault Indicator Output for Channel B. This open-drain output goes low when channel B is in
thermal shutdown or in undervoltage lockout or in a sustained (>20ms) current-limit or short-circuit
condition.
Current-Limit Adjust for Channel B. When operating from auxiliary input, adjust the current limit by
connecting a resistor from ADJB to GND as shown in Programmable Current Limit .
Power Output B. Connect both OUTB_ pins together. Connect a 1μF or greater capacitor from
OUTB_ to ground. Load condition may require additional bulk capacitance.
Power Output A. Connect both OUTA_ pins together. Connect a 1μF or greater capacitor from
OUTA_ to ground. Load condition may require additional bulk capacitance.
