PWM controller UC3843

Former Member
Former Member over 15 years ago

On Texas Instruments website the UC3843 controller is suggested also for Buck topology, but UC2843 is just for Boost, Flyback and Forward.

 

Can anyone tell me what is the difference between them and why only UC3843 is okay for Buck converters?

 

Thanks

    The only different is the temperature range.  The 3843 has 0-70C, while the 2843 has -40-85C.
