Part Number: LM3643 Hi Support team
This is related to one of my previous questions, customer is asking for minimum input and output capacitance for stability, thanks Jeff Coletti
Part Number: LM3643 hi, This is Martin from Intel Shanghai, we use LM3643 in Intel reference design to drive camera flash led. from datasheet, it support GPIO HW trigger in torch mode, if no GPIO is available for torch, can LM3643 support I2C trigger to…
Part Number: LM3643 Hi,
Customer would like to confirm if LM3643 is no problem to connect LED1, LED2 together to drive one LED?
Best regards,

Part Number: LM3643 Hi team,
I have a question about LM3643.
Can LM3643 drive red led?
Vf of red led is 2.4V and LM3643 has pass mode so I think LM3643 can drive red led but my concern is thermal issue.
e.g.
Vin=5V
ILED=1.5A
Vf=2.4V(red led)
Voltage…
Part Number: LM3643 Hi,
Customer would like to confirm if it is OK to tie the HWEN and TX pin together? and tie the STROBE and TORCH/TEMP pin together? Any concern or side effect?
Best regards,

Part Number: LM3643 Other Parts Discussed in Thread: LM3644 My customer has asked:
In one of our products we are using LM3643 LED driver.
I was looking at the datasheet and noticed the current “ramp up/down” for ~ 1ms on LED current.

Part Number: LM3643 Hi All,
First let me sketch the situation:
I have design to perform some test where I use 18 LM3643 to control 18 leds. Too individually control every single device, the I2C bus is muxed with an analog mux, which works as expected…
Part Number: TLC59116 Other Parts Discussed in Thread: LM3643 , LM3565 , LM2754 , In a application I need to design, I would like to control 60 LEDs individually via i2c preferably in flash mode.
Drivers such as LM3565 LM3643 LM2754 that support flash can…
