Part Number: LM3644 Other Parts Discussed in Thread: TPS92201 Hello Expert,
Is there a way to keep ON at FLASH and IR MODE regardless of TIME OUT?
Isn't it possible?
Best Regards,
Michael
Part Number: LM3644 Regarding the LM3644YFFR LED driver, would you like to confirm if it is our main control unit that can be disconnected from the B2/C2/C3/D2 pins, And completely using I2C for control?
The specification states that the function of LM3644…

Part Number: LM3644 Hi team,
if Vin=0, Vout is high, can LM3644 block Vout to go into VIn?
from datasheet, the sync MOS is a PMOS, body diode is from SW to Vout, then it should be able to block the voltage from Vout into Vin. Is it right? thanks.

Part Number: LM3644 Other Parts Discussed in Thread: TCA9548A Hi Team,
I am looking for a simulation model of LM3644. Do we have any available for Pspice of TINA? I found no available in TI.com. I was wondering if there is any available on your side.

Part Number: LM3644 Hi,
I would like to use LM3644 to strobe VCSEL at its typical If=600mA. In this condition the VCSEL's Vf=2V.
1. Is LM3644 suitable to drive a LED/VCSEL with Vf lower than 2.3V?
2. What is the lowest Vf supported by this IC?
I found…
Part Number: LM3644 Hi Expert,
Is the value of Last Flash Register (0x0D) only a setting value? or a real driving current value?
I read back Register (0x0D) value in flash mode, but the value is always 0x7F, no change in value.
It is really not like t…
