LTM4601AHV
pin FuncTions (See Package Description for Pin Assignment) COMP (Pin A11):
Current Control Threshold and Error off the module. A programmable UVLO function can be Amplifier Compensation Point. The current comparator accomplished by connecting to a resistor divider from threshold increases with this control voltage. The voltage VIN to ground. See Figure 1. This pin has a 5.1V Zener to ranges from 0V to 2.4V with 0.7V corresponding to zero ground. Maximum pin voltage is 5V. Limit current into the sense voltage (zero current). RUN pin to less than 1mA.
PGOOD (Pins G12, F11):
Output Voltage Power Good
VOUT_LCL (Pin L12):
VOUT connects directly to this pin to Indicator. Open-drain logic output that is pulled to ground bypass the remote sense amplifier, or DIFFVOUT connects when the output voltage is not within ±10% of the regula- to this pin when the remote sense amplifier is used. tion point, after a 25µs power bad mask timer expires.

RUN (Pin A10):
Run Control Pin. A voltage above 1.9V ing Pads. These pads must be left floating (electrical open will turn on the module, and when below 1V, will turn circuit) and are used for enhanced solder joint strength.
