PIN FUNCTIONS
COMP (Pins A11, D11): Current Control Threshold and Er-
ror Amplifi er Compensation Point. The current comparator
threshold increases with this control voltage. The voltage
ranges from 0V to 2.4V with 0.7V corresponding to zero
sense voltage (zero current).
PGOOD (Pin G12): Output Voltage Power Good Indicator.

output voltage is not within ±10% of the regulation point,
after a 25μs power bad mask timer expires.
RUN (Pins A10, B9): Run Control Pins. A voltage above
1.9V will turn on the module, and below 1V will turn off
the module. A programmable UVLO function can be ac-
complished with a resistor from V
5.1V zener to ground. Maximum pin voltage is 5V.
