Hello,
My customer searching LED driver for Automotive of below requirement spec.
<Requirement>--------------------------
Rating : Automotive
Number of Channel : 5 channel
Vin : 5V or 8V
Vout : 4V(max)、30.1V(max)
Iout / ch : 50mA(typ)、55mA(max)
Iout / ch : 50mA(typ)、55mA(max)
------------------------------------------------
I can find LM3431Q as 3ch of LED driver IC.
I thought that if I can use 2pcs of LM3431Q , we can make above requirement LED driver circuit.
1.
Can LM3431Q operate above ?
2.
If I use 2 device of LM3431Q for 5channel , are there LED current variation ?
Are there any application note for control the LED current variation ?
3.
If there are any other device for this requiremnt , please kindly let me know?
Best Regards,
Ryuji Asaka
