Part Number: TLC6A598

Dear Team,

Our customer need a LED driver to drive attached LED lighting, can you help me to find the suitable solution?

Make sure the IC spec can be met with the attached LED with following parameter.

Vin=4.5V in our side
Vout to support attached LED with voltage 2.65V to 3.55V
Current rate should be at least 1A.
Signal control: PWM type
Operating temperature:-40~85oC

Many Thanks,

Jimmy

The max current for each channel is 350mA. they should parallel 3-4 channels to achieve the current.

i want to know which customer need this, and what's the EE for this project?

Hi Jimmy.

Since TLC6A598 is a high-reliability driver for avionic applications and cost $5 each which is a little expensive for normal LED driver, I'm pretty interested in the detailed introduction of this customer 'Ubiquiti networks' and what they need this LED driver for. Also, I notice that

Jimmy Lai said:
Current rate should be at least 1A.

the demanding current rate is really large and is not a common need. Why do they need such large current? I also wonder if they have RGB need.

Besides, what's the quantity of their needs?

You can directly mail to me.

Gracie.
