Electrical Specifications
Functional Pin Description (QFN/SOIC)
SS (Pin 1/3)
Connect a capacitor from this pin to ground. This capacitor,
along with an internal 30µA current source, sets the soft-start
interval of the converter.
COMP (Pin 2/4) and FB (Pin 3/5)
COMP and FB are the available external pins of the error
amplifier. The FB pin is the inverting input of the error
amplifier and the COMP pin is the error amplifier output.
These pins are used to compensate the voltage-control
feedback loop of the converter.

VCC
EN (Pin 4/6)
This pin is a TTL compatible input. Pull this pin below 0.8V to
disable the converter. In shutdown the soft-start pin is
discharged and the TGATE and BGATE pins are held low.
REFIN (QFN ONLY Pin 5)
Upon enable if REFIN is less than 2.2V, the external
reference pin is used as the control reference instead of the
internal 0.597V reference. An internal 6µA pull-up to 5V is
provided for disabling this functionality.
GND (Pin 6/7)
Signal ground for the IC. All voltage levels are measured
with respect to this pin.
