FUNCTION
Power supply Input of switch 1. Connect this pin to an external DC supply.
Enable input of switch 1. Logic high turns on switch 1. The EN1 pin cannot be left floating.
Bias voltage input pin for internal control circuitry.
Enable input of switch 2. Logic high turns on switch 2. The EN2 pin cannot be left floating.
Power supply Input of switch 2. Connect this pin to an external DC supply.
Switch 2 output.
Soft start control of switch 2. A capacitor from this pin to ground sets the VOUT2’s rise slew
rate.
Ground pin of the circuitry. All voltage levels are measured with respect to this pin.
Soft start control of switch 1. A capacitor from this pin to ground sets the VOUT1’s rise slew
rate.
Switch 1 output.
