Remote Sense
To minimum the effects of distribution losses by regulating the voltage at the Remote Sense pin. The voltage between the SENSE
pin and OUTPUT pin must not exceed 10% of Vout, i.e.
[ +OUTPUT to –OUTPUT ] – [ +SENSE to –SENSE ] < 10% Vout
The voltage between +OUTPUT and –-OUTPUT terminals must not exceed the minimum output overvoltage protection threshold.
This limit includes any increase in voltage due to remote sense compensation and trim function.
If not using the remote sense feature to regulate the output at the point of load, then connect +SENSE to +OUTPUT and –SENSE
to –OUTPUT.

Input Source Impedance
The power module should be connected to a low impedance input source. Highly inductive source impedance can affect the stability
of the power module. Input external π lter is recommended to minimize input reected ripple current. The inductor is simulated
source impedance of 12μH and capacitor is Nippon chemi-con KY series 100μF/100V. The capacitor must as close as possible to
the input terminals of the power module for lower impedance.
