Current-Mode Controller, Fixed Frequency, for Two-Switch Forward Converter
The NCL30125 is a fixed- frequency current- mode controller featuring the Dynamic Self- Supply (DSS). This function greatly simplifies the design of the auxiliary supply and the VCC capacitor by activating the internal startup current source to supply the controller during start- up, transients, latch, stand- by etc.
With a supply range up to 35 V, the controller hosts an adjustable switching frequency with jittering function operated in peak current mode control. When the power on the secondary side drops drastically, the part enters skip cycle while limiting the peak current that...
