NCP1055 regulator equivalent, monolithic high voltage gated oscillator power switching regulator.
an active startup regulator circuit that eliminates the need for an auxiliary bias winding on the converter transformer, fault detector and a programmable timer for conve.
they are capable of providing an output power that ranges from 6.0 W to 40 W with a fixed AC input of 100 V, 115 V, or 2.
