LTM4603HV
pin FuncTions (See Package Description for Pin Assignment) VFB (Pin F12):
The Negative Input of the Error Amplifier.
COMP (Pin A11):
Current Control Threshold and Error Internally, this pin is connected to VOUT_LCL with a 60.4k Amplifier Compensation Point. The current comparator precision resistor. Different output voltages can be pro- threshold increases with this control voltage. The voltage grammed with an additional resistor between VFB and ranges from 0V to 2.4V with 0.7V corresponding to zero SGND pins. See the Applications Information section. sense voltage (zero current).
MARG0 (Pin C12):
This pin is the LSB logic input for the
PGOOD (Pin G12):
Output Voltage Power Good Indicator. margining function. Together with the MARG1 pin will Open-drain logic output that is pulled to ground when the determine if margin high, margin low or no margin state output voltage is not within ±10% of the regulation point, is applied. The pin has an internal pull-down resistor of after a 25µs power bad mask timer expires. 50k. See the Applications Information section.
RUN (Pin A10):
Run Control Pin. A voltage above 1.9V
MARG1 (Pin D12):
This pin is the MSB logic input for the will turn on the module, and when below 1V, will turn margining function. Together with the MARG0 pin will off the module. A programmable UVLO function can be determine if margin high, margin low or no margin state accomplished by connecting to a resistor divider from is applied. The pin has an internal pull-down resistor of VIN to ground. See Figure 1. This pin has a 5.1V Zener to 50k. See the Applications Information section. ground. Maximum pin voltage is 5V. Limit current into
SGND (Pin H12):
Signal Ground. This pin connects to the RUN pin to less than 1mA. PGND at output capacitor point.
VOUT_LCL (Pin L12):
VOUT connects directly to this pin to bypass the remote sense amplifier, or DIFFVOUT connects to this pin when remote sense amplifier is used. 4603hvfa 8 For more information www.linear.com/LTM4603HV Document Outline Features Applications Description Typical Application Absolute Maximum Ratings Pin Configuration Order Information Electrical Characteristics Typical Performance Characteristics Pin Functions Block Diagram Decoupling Requirements Operation Applications Information Typical Applications Package Description Revision History Related Parts
