TL2844: difference

sundy xie
Intellectual 525 points
Part Number: TL2844

Dear,

Could you help to check the difference of TL2844BDR-8 and UC2844BD1(ST)?

We want to replace UC2844BD1 with TL2844BDR-8 directly.

    Hello sundy xie,
    The TI part UC2844D was the first marketed part in this family of parts..
    These parts were so successful as PWM controllers that a number of ic manufacturers began to manufacture similar parts with a pin to pin compatibility. I believe the UC2844BD1 is the ST equivalent to the UC2844D and the TL2844BDR-8
    Even though these parts are marketed as being equivalent, you will still need to review the datasheet parameters and check to see if any difference in limits will affect your design requirements. Then you will need to replace the old part with the new part and test your product to ensure that it meets all of your requirements. Unfortunately there is no quick and easy way around this.
    The new part will most likely work satisfactorily but you will need to check and sure that it does.
    Hope this answers your question
    Regards
    John
