An over-current trip cycles the soft-start function.
SS (Pin 3)
Connect a capacitor from this pin to ground. This capacitor,
along with an internal 10 μ A current source, sets the soft-
start interval of the converter.

VID0-4 (Pins 4-8)
VID0-4 are the input pins to the 5-bit DAC. The states of
V SEN (Pin 1)
This pin is connected to the converters output voltage. The
PGOOD and OVP comparator circuits use this signal to
report output voltage status and for overvoltage protection.
OCSET (Pin 2)
Connect a resistor (R OCSET ) from this pin to the drain of the
upper MOSFET. R OCSET , an internal 200 μ A current source
(I OCS ), and the upper MOSFET on-resistance (r DS(ON) ) set
these five pins program the internal voltage reference
(DACOUT). The level of DACOUT sets the converter output
voltage. It also sets the PGOOD and OVP thresholds. Table
1 specifies DACOUT for the all combinations of DAC inputs.
COMP (Pin 9) and FB (Pin 10)
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.
