onsemi NCL30125
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.| Part No. | NCL30125 |
