Part Number: LM2758 Hello SIrs,
For this LED driver , may I have your comment what's max torch/flash current ?
Can Rset below 10K ohm ? If its OK, why D/S Fig.6 show Rset range start from 10K ohm ?
Many thanks a lot !
Part Number: LM2758 Hello, If we use this device with TORCH mode only, we set EN1 pin to "0" always. In this case, can we connect EN1 pin to GND without pull down resistor? Or, since the device has pull down 500kohm resistor, can be left floating…
Part Number: LM2758 Hello
I have some questions about LM2758. Our customer request the following specification LED drive and I promoted LM2758. LED 1pcs, Vout=4.2~5V, Vin=3.2V~4.2V, 40mA, as small as possible package, stand alone control
(1) minimum LED…
Other Parts Discussed in Thread: LM2758 , LM3553 LM2758 has three modes to turn on LED, such as Flash, Torch and Indicator mode.
LM2758 datasheet says Indicator Current Level is typical 20mA. Is it possible to adjust this current level for Indicator mode…
Other Parts Discussed in Thread: LM2758 I have a question.
We checked the accuracy of flash mode in the data sheet 4 page.
We checked the accuracy ±50mA(±10%) of 500mA flash mode.
But,we need the accuracy in torch mode.
Please teach the current…
Other Parts Discussed in Thread: LM2758 Could you let me know the period that we should hold the EN pin to Low for reset the Flash-Time out?
Our customer would like to turn on the Flash again as quick as possible after Flash Time-Out.
The target value…
Hello,
The LM3643 should be able to behave in a manner like the LM2758. The customer would need to set the flash level equal to the peak torch level desired, and then will have to pulse the strobe pin at 40kHz and a 1/32 duty cycle to match the pattern…
