Low VIN, 8A DC/DC µModule Regulator with Tracking, Margining, and Frequency Synchronization

Linear Technology 

LTM4608A

PIN FUNCTIONS

FB (E7): The Negative Input of the Error Amplifier. Internally,

this pin is connected to VOUT with a 10k precision resistor.

Different output voltages can be programmed with an ad-

ditional resistor between FB and GND pins. In PolyPhase®

operation, tie FB pins together for parallel operation. See

the Applications Information section for details.

ITH (F6): Current Control Threshold and Error Amplifier

Compensation Point. The current comparator threshold

increases with this control voltage. Tie together in parallel

operation.

ITHM (F5): Negative Input to the Internal ITH Differential

Amplifier. Tie this pin to SGND for single phase operation.

For PolyPhase operation, tie the master’s ITHM to SGND

while connecting all of the ITHM pins together.

PGOOD (C7): Output Voltage Power Good Indicator.

Open-drain logic output that is pulled to ground when the

output voltage is not within ±10% of the regulation point.

Disabled during margining.

RUN (F1): Run Control Pin. A voltage above 1.5V will turn

on the module.

SW (C3-C5): Switching Node of the Circuit is Used for

Testing Purposes. This can be connected to an electri-

cally open circuit copper pad on the board for improved

thermal performance.

CLKOUT (F2): Output Clock Signal for PolyPhase Opera-

tion. The phase of CLKOUT is determined by the state of

the PHMODE pin.
