Part Number: LM3642 Hi, Team
I am studying on LM3642 flash driver. The datasheet mentions: On start-up, when VOUT is less than VIN the internal synchronous PFET turns on as a current source and delivers 350 mA (typ.) to the output capacitor, like below…
HI ,
We are using LM3642TLX-LT/NOPB (low torch current ) variant as Camera Flash chip in our custom design .
The LED current is set for Max. value =187.5mA . The IR LED connected at pin VLED (pin B1) without any series resistor .
The battery voltage…
Hello,
With the LM3642, the mode bits reset at the end of any flash event regardless if the part hits time-out or not. I don't believe there is any way to bypass this.

Part Number: LM36274 Other Parts Discussed in Thread: LM3642 Hi Team,
just want to check on what's the difference between below two parameters? what does it means " device not switching pass mode" ? Thanks.

Hi Gjellan,
Since the input voltage is lower or little higher than required output, boost or pass mode is needed. How about LM3642? This device starts with pass mode, and when the difference between VIN and VOUT is larger than threshold, device switches…
Other Parts Discussed in Thread: LM3642 , LM3644 Hi,
My customer use LM3644TT, but they do not know how to initial the communication with Qualconn chip.
Do We have reference initial code for Qualconn platform?
Now they are testing LM3642 initial…
