PIN FUNCTIONS
LTM4601A/LTM4601A-1
MARG1 (Pin D12): This pin is the MSB logic input for the
margining function. Together with the MARG0 pin will
determine if margin high, margin low or no margin state
is applied. The pin has an internal pull-down resistor of
50k. See Applications Information.
SGND (Pins H12, H11, G11): Signal Ground. These pins
connect to PGND at output capacitor point. See Figure 15.
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 (Pins G12, F11): Output Voltage Power Good
Indicator. Open-drain logic output that is pulled to ground
when the output voltage is not within ±10% of the regula-
tion 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 ac-
complished with a resistor from V
5.1V zener to ground. Maximum pin voltage is 5V. Limit
current into the RUN pin to less than 1mA.
