IMONb (C1): Power Inductor Analog Indicator Current De-

fault Termination R-C Network. A 10kΩ resistor in parallel

with a 10nF capacitor and terminating to SGND connect

to this pin. Connect IMONb to IMONa to achieve default

power inductor analog indicator current characteristics:

1V at full scale (4A) load current. (See IMONa.)

TEMP+ (J1, J6): Temperature Sensor, Positive Input.

Emitter of a 2N3906-genre PNP bipolar junction transis-

tor (BJT). Optionally interface to temperature monitor-

ing circuitry such as LTC®2997, LTC2990, LTC2974 or

LTC2975.Otherwiseleaveelectricallyopen.PinsJ1andJ6

areelectricallyconnectedtogetherinternaltotheLTM4653,

and thus it is only necessary to connect one TEMP+ pin

to monitoring circuitry. The remaining TEMP+ pin can be

used for redundant connectivity or routed to an ICT test

point for design-for-test considerations, as desired.

TEMP– (J2, J7): Temperature Sensor, Negative Input.

Collector and base of a 2N3906-genre PNP bipolar junc-

tion transistor (BJT). Optionally interface to temperature

monitoringcircuitrysuchasLTC2997, LTC2990,LTC2974

or LTC2975. Otherwise leave electrically open. Pins J2

and J7 are electrically connected together internal to the

LTM4653, and thus it is only necessary to connect one

TEMP– pin to monitoring circuitry. The remaining TEMP–

pin can be used for redundant connectivity or routed to an

ICTtestpointfordesign-for-testconsiderations,asdesired.

SW (H4): Switching Node of Switching Converter Stage.

Used for test purposes. May be routed a short distance

with a thin trace to a local test point to monitor switching

action of the converter, if desired, but do not route near any

sensitivesignals;otherwise,leaveelectricallyopencircuit.

NC (A6-7, B2, B6-7, C6-7, D6-7, E6-7, F6-7, G6-7, H6-7,

K6-7, L6-7): No connect pins, i.e., pins with no internal

connection. The NC pins predominantly serve to provide

improved mounting of the module to the board. In one’s

layout, NC pins are permitted to remain electrically uncon-

nected or can be connected as desired, e.g., connected

to a GND plane for heat-spreading purposes and/or to

facilitate routing.
