Current-mode PWM controller for isolated power supplies
The 5962-8670405PA is a UC1842A current mode PWM controller, designed for off-line and DC-to-DC converter applications requiring tight output regulation and cycle-by-cycle current limiting.
Bulk packaging and procurement fit
Supplied in bulk format — the loose-tube or tray packaging suits low-to-medium volume assembly and prototyping without reel minimums.
Peer comparison for second-source evaluation
The UCC2806DWTR targets boost, flyback, and forward topologies with dual outputs and a 50% duty cycle limit — functionally different from the single-output current-mode architecture of the UC1842A. The LM51231QRGRRQ1 is an automotive-grade boost controller with AEC-Q100 qualification and 2.2 MHz switching — suited for automotive step-up designs but not a direct functional equivalent for the 5962-8670405PA.
