Guru 17990 points
Part Number: TPS92210
Other Parts Discussed in Thread: PMP6023

I looking for below LED driver condition.

・Input:415V AC/DC

・Vout and Iout:TBD

・Need to 0%~100% dimming control

If there match device, please let me know.

Or, I think that close solution is PMP6023, is there way to use 415Vin condition?

Best regards,

Satoshi

  • Hello Satoshi,
    I was unable to find a TI reference design with an operating input of 415V
    The PMP9063 can be modified to work at this voltage but several of the components need to be changed.
    For example the voltage rating of C1,C2,C3,RV1,Q1,D9 and D5 would need to be reviewed.
    Also the isolation voltage of T1 should be looked at.
    Hope this helps
    Regards
