When choosing appropriate values for R
SENSE
a compromise must be reached between in-line
signal loss (including potential power dissipation effects) and small signal accuracy.
Higher values for R
SENSE
gives better accuracy at low load currents by reducing the inaccuracies
due to internal offsets. For best operation the ZXCT1041 has been designed to operate with
V
SENSE
of the order of 50mV to 150mV.
