Hi Team,

May I know what the difference between UC2844A and UC2844 is?

In the datasheet of UC2844, I saw the Fosc = 2* Fsw.

In the datasheet of UC2844A, I can't see the Fosc = 2* Fsw. What is the relationship of Fosc and Fsw?

Thanks!

Hello Eggsy,

The UC2842, UC2843 and the UC2842A, UC2843A have a 100% max duty cycle and Fosc = Fsw

The UC2844, UC2845 and the UC2844A, UC2845 have a 50% max duty cycle and Fosc = 2*Fsw

Regards

John
