LTM4601/LTM4601-1
PIN FUNCTIONS
SGND (Pin H12): Signal Ground. This pin connects to
PGND at output capacitor point.
COMP (Pin A11): Current Control Threshold and Error
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.
Open-drain logic output that is pulled to ground when the
output voltage is not within ±10% of the regulation point,
after a 25μs power bad mask timer expires.

RUN (Pin A10): Run Control Pin. A voltage above 1.9V
will turn on the module, and when below 1.9V, will turn
off the module. A programmable UVLO function can be
accomplished with a resistor from V
a 5.1V Zener to ground. Maximum pin voltage is 5V. Limit
current into the RUN pin to less than 1mA.
