Description
This pin is part of the error amplifier and provides the
reference voltage which the sampled output voltage is
compared to. A difference between these two
voltages indicates an error in the output voltage.
This pin provides the error amplifier output which
compensates for errors in the output voltage identified
using the FB pin.
Gate drive for external upper MOSFET (Ipeak<200 mA;
Iavg<20 mA)
Gate drive for external lower MOSFET (Ipeak<200 mA;
Iavg<20 mA)
3.3 V power supply only for gate driver of SW
(Ipeak<200 mA; Iavg<20 mA)
3.3 V analog power (Ipeak<200 mA; Iavg<10 mA)
Connect to Base terminal of external BJT (Iavg<20 mA)
