Part Number: LM3648 Hi team,
One of my customer is using LM3468 and the schematic is as attached.
The LED works between 2.5-3V and they want LM3468 to work in pass mode . But in actual test , some LEDs can work normally and some can't. I guess that…
Part Number: LM3648
The device was reset abnormally. There is about a 5 percent probability after power-on. Could you please help analyze the reason?
The attachment has some information. LM3648 register value shown in ““normal_register” during normal…
Part Number: LM3644 Other Parts Discussed in Thread: LM3648 Hi Sirs,
May I know the LM3644 can connect 2-ch to drive one LED(peak current max = 2A)?
It means we will use it to do the 2nd source device for the LM3648.
Part Number: LM3648 Hi Team
Customer are wondeing if lm3648yffr chip:
1. Whether REACH standard is met?
2. What is the humidity sensitivity level of MSD?
The above is not stated in the datasheet specification, could you please help to provide…
Part Number: LM3648 Dear TI Experts,
May I know the work frequency and Minimum Pulse Width(include minimum rising time and minimum falling time) in IR Mode? Thanks a lot.
Part Number: LM3648 Hi sirs,
Do we have the 1.5A LED flash driver without I2C interface? The flash LED current is programmable by resistor. Thanks!
Best regards,

Hello,
Red LEDs can be driven with this part. The only concern is thermal management. With 3.3V in and an LED of 2V, @ 500mA of current the part will dissipate 650mW. With a thetaJA of 90.2degC/W, you can expect a die temp rise of at least 58 degC over…
