UCC2818-EP: Extremely low temperature operation

Part Number: UCC2818-EP
Other Parts Discussed in Thread: UC1854, UC2854B-EP

Hello team,

Does UCC2818-EP works in extremely low temperature condition (-54degC)?

I'm looking for generic PFC controller which works in -54degC condition.

Also, the PFC controller needs to accept both AC and DC input.

Does TI have good part?

Hello Yunsheng-san,

Thank you so much.

Could you please check if UC1854 and UC2854B-EP accept DC input as well?

I think they should work in -54degC environment.
