Part Number: LM3643
This is the schematic i used. For IN I attached a power supply with around 3.6v .
Register Name
Address
Value (Hex)
Purpose
LED2 Torch Brightness
0x06
0x00
Sets LED2 to 0.977…
Part Number: LM3643 Tool/software: If we only use Torch mode (~100mA), can the L1 inductor be replaced with a type that has a lower Isat (e.g., 500mA)?
Part Number: LM3643 Hi,
Due to some space limitation I`m forced to use the LM3643 without the output cap on PASS mode.
Looks to be only a bit of undershoot.
Did someone use the same configuration ?
Thanks
Luci
Part Number: LM3643 Hi team,
1. if the TX is high forever, do this mean we can't enter flash mode right?
2. what would happen if TORCH/TEMP and STROBE both high, what will IC react base on if I2C enable register is torch mode ?
thanks
Part Number: LM3643 Other Parts Discussed in Thread: LM3648 , LM36010 Hi Sir,
We knew the LM3643 and LM3648 both have same I2C address= 0x63. My customer and I are trying to figure out the differences between the LM3643 and LM3648TT. They have ever…
Part Number: LM3643 Hi Sir,
My customer would like to add an external P-MOS to do the LED switch. Could you please help to review the below schematics and advise comments? My customer also has some questions as below. The default condition is the LED…
Part Number: LM3643LM3643 is used to drive LED. its input 5VDC supplied by AC/DC adaptor. 5VDC has long transmission line, 4m long with #AWG22 wires. To protect LM3643, TVS D5V0F1U2S9-7 is used to avoid ESD, surges or coupled spikes. Yet, there are still…
Part Number: LM3643LM3643_TRANS simulation schematic is used as starting point. Pspice model of LM3643 property is modified so that it runs at IR mode. Input DC voltage source is changed from 3.6V to 5V. Pulse th at feeds Strobe pin is V1=0, V2= 3.3…
