The BiCMOS internal reference of 2.5 V has an enhanced design, and uses production trim to allow initial accuracy of ±1% at room temperature and ±2% over the full temperature range. This reference voltage can be used to eliminate an external reference in applications that do not require the extreme accuracy afforded by the additional device. This reference voltage is useful for non-isolated DC-DC applications, where the control device is referenced to the same common as the output. It is also applicable in off-line designs that regulate on the primary side of the isolation boundary by looking at a primary bias winding, or from a winding on the output inductor of a buck-derived circuit.
