PIN FUNCTIONS (See Package Description for Pin Assignment) MARG1 (Pin D12):
This pin is the MSB logic input for the
RUN (Pin A10):
Run Control Pin. A voltage above 1.9V margining function. Together with the MARG0 pin it will will turn on the module, and when below 1V, will turn determine if margin high, margin low or no margin state off the module. A programmable UVLO function can be is applied. The pin has an internal pull-down resistor of accomplished by connecting to a resistor divider from 50k. See the Applications Information section. VIN to ground. See Figure 1. This pin has a 5.1V Zener to
SGND (Pins H12, H11, G11):
Signal Ground. These pins ground. Maximum pin voltage is 5V. Limit current into connect to PGND at output capacitor point. See Figure 15. the RUN pin to less than 1mA.
COMP (Pin A11):
Current Control Threshold and Error
VOUT_LCL (Pin L12):
VOUT connects directly to this pin to Amplifier Compensation Point. The current comparator bypass the remote sense amplifier, or DIFFVOUT connects threshold increases with this control voltage. The voltage to this pin when the remote sense amplifier is used. ranges from 0V to 2.4V with 0.7V corresponding to zero VOUT_LCL can be connected to VOUT on the LTM4601A-1, sense voltage (zero current). VOUT is internally connected to VOUT_LCL with 50Ω in the LTM4601A-1.
PGOOD (Pins G12, F11):
Output Voltage Power Good Indicator. Open-drain logic output that is pulled to ground
MTP1, MTP2, MPT3 (Pins C10, D10, D11 ):
Extra Mount- when the output voltage is not within ±10% of the regula- ing Pads. These pads must be left floating (electrical open tion point, after a 25µs power bad mask timer expires. circuit) and are used for enhanced solder joint strength. 4601afe 8 For more information www.linear.com/LTM4601A Document Outline Features Applications Description Typical Application Absolute Maximum Ratings Pin Configuration Electrical Characteristics Typical Performance Characteristics Pin Functions Simplified Block Diagram Decoupling Requirements Operation Applications Information Typical Applications Package Description Revision History Package Photos Related Parts
