PIN FUNCTIONS FB (E7):
The Negative Input of the Error Amplifier. Internally,
PGOOD (C7):
Output Voltage Power Good Indicator. this pin is connected to VOUT with a 10k precision resistor. Open-drain logic output that is pulled to ground when the Different output voltages can be programmed with an ad- output voltage is not within ±10% of the regulation point. ditional resistor between FB and GND pins. In PolyPhase® Disabled during margining. operation, tie FB pins together for parallel operation. See
RUN (F1):
Run Control Pin. A voltage above 1.5V will turn the Applications Information section for details. on the module.
ITH (F6):
Current Control Threshold and Error Amplifier
SW (C3-C5):
Switching Node of the Circuit is Used for Compensation Point. The current comparator threshold Testing Purposes. This can be connected to an electri- increases with this control voltage. Tie together in parallel cally open circuit copper pad on the board for improved operation. thermal performance.
ITHM (F5):
Negative Input to the Internal ITH Differential
CLKOUT (F2):
Output Clock Signal for PolyPhase Opera- Amplifier. Tie this pin to SGND for single phase operation. tion. The phase of CLKOUT is determined by the state of For PolyPhase operation, tie the master’s ITHM to SGND the PHMODE pin. while connecting all of the ITHM pins together. 4608afe 8 For more information www.linear.com/LTM4608A Document Outline Features Applications Description Typical Application Absolute Maximum Ratings Order Information Typical Performance Characteristics Pin Functions Simplified Block Diagram Operation Applications Information Typical Applications Package Description Package Photo Revision History Package Description Related Parts
