PIN FUNCTIONS
(See Package Description for Pin Assignment)
SGND (Pin H12): Signal Ground. This pin connects to
PGND at output capacitor point. See Figure 15.
COMP (Pin A11): Current Control Threshold and Error
Amplifier 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 1V, will turn
off the module. A programmable UVLO function can be
accomplished by connecting to a resistor divider from
V IN to ground. See Figure 1. This pin has a 5.1V Zener to
ground. Maximum pin voltage is 5V. Limit current into the
RUN pin to less than 1mA.
V OUT_LCL (Pin L12): V OUT connects directly to this pin
to bypass the remote sense amplifier, or DIFFV OUT con-
nects to this pin when the remote sense amplifier is used.
V OUT_LCL can be connected to V OUT on the LTM4601-1,
V OUT is internally connected to V OUT_LCL with 50 W in the
LTM4601-1.
