Note 1:The module can be trimmed down 30% and trimmed up 7% at all temperature condition.
The module can be trimmed down 40% at 25°C and minimum reference temperature. At least 10% of normal output current is suggested when it is
trimmed down 40% at maximum reference temperature. The module can be trimmed up 10% at 25°C and minimum reference temperature. When input
voltage below 48V, at most 65% of normal output current is suggested in case it is trimmed up 10% at maximum reference temperature.
