Part Number: LM3644 Tool/software: Hi All,
We used the LM3644 to drive LED in Torch mode.
But we find the torch mode can't be set at some devices.
We have checked the schematic, the Torch pin and Strobe pin are floating.
Do those two pins need to…
Part Number: LM3644 Tool/software: Hi
I'm looking for a VCSEL driver with photodiode(PD) detection function.
Since VCSEL is a high-power density light source, PD is needed to detect whether the VCSEL package is damaged, causing laser light to overflow…

Is there a way to keep ON at FLASH and IR MODE regardless of TIME OUT?
Isn't it possible?
Best Regards,

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.
