Part Number: LM3492 Hi,
is the LM3492 suitable for a SEPIC design? The datasheet mentions the projected-on-time feature. Would that interfere with the SEPIC topology?
By now I have used the LM3492 in the normal Boost configuration and it works fine.…
Part Number: LM3492 HI colleagues,
my customer what to use the integrated LDO from the LM3492 to power external components.
What is the maximum load you can connect the Vcc pin.
Best regards,
Florian
Hello,
At first, I would like to make sure what is our concerning point.
It is NOT matter for us that it doesn't boost the input voltage to light LED strings.
Our targeting LED's Vf figure is including range in individual differences and we know…
Part Number: LM3492-Q1 Other Parts Discussed in Thread: LM3492EVAL , Hi Tier
LM3492-Q1 use process is as follows(tools LM3492EVAL )。
power on LM3492EVAL, work normally, open LED load, Connect LED load,power off LM3492EVAL .
The device is damaged after…
Part Number: LM3492 Hi all Would you mind if we ask LM3491? Our customer would like to use LM3492 with LED current=230mA×2, however the current is upto 200mA at each output port. Just in case, is it impossible to configure this? Kind regards, Hirotaka …
Part Number: LM3492 Tool/software: WEBENCH® Design Tools I am using the LM3492 to drive 2 strings of 9 LEDs per string. the LED Vf is 3.2volts and string voltage is 28.8V
Input power is 12VDC. The current is 20mA per string
The Webbanch gave me a design…

Hi team
I will ask the question below.
Q1
I want to use dim1 and dim2 together. Please share your notes when using them together.
Q2
The PWM voltage level is 0 to 5V. Is it usable?
Q3
Please share data related to junction tempe…
Part Number: LM3492 Other Parts Discussed in Thread: LM5112 Dear people
I have connected the two dimming Pins (DIM1 and DIM2) together to one PWM Input channel and want to use it to pulse two LED chains connected to IOUT1 and IOUT2.
So I have three connections…
Part Number: LM3492 Hi all Would you mind if we ask LM3492? How much are the maximum and minimum frequency of DIM1 and DIM2 pins? We guess that Maximum : 300ns Minimum : not in particular? Kind regards, Hirotaka Matsumoto
Part Number: LM3492 Other Parts Discussed in Thread: TPS92561 Hi,
I am designing a luminaire with LEDs (VF=6.1V, IF=100mA) using LM3492 based on following:
- Vin= 24Vac to 32Vac
- Iout (300mA) , Vout (42.7V)
I am currently implementing the configure 7…
