Part Number: LM3492HC Other Parts Discussed in Thread: LM3492 Hi TI Support team,
The LM3492HC provides thermal protection, over-power protection and limit output voltage. This over-power protection feature avoids damaging the current regulator owing…
Part Number: LM3492HC-Q1 Other Parts Discussed in Thread: LM3410-Q1 I have six LEDs I want to power. They have a 1.1Vmin to 1.9V max Vfw with a 1.65V typical Vfw, and I'm going to drive them at 70mA. So I feel like this is a decent part and I can just…
Part Number: LM3492HC-Q1 Hello Team,
Attached below is the design for LM3492HC-Q1 IC. The parameters considered are Vin= +12V ; Vout= +24.3V; Iout = 120mA. Kindly help me verify this design.

Part Number: LM3492HC Hi All,
I have a question about the LM3492HC.
Does the LM3492HC have Open LED Protection? Does the MOSFET keep turning off when other protection functions operate? Or will it automatically recover?
Best Regards, Ishiwata
Hi TI support team,
For 250 mA, the content of datasheet is as follows:
It says the LM3492HC can support 250 mA per channel. Can you confirm it.
For Iin(min), the content of EVB datasheet is as follows:
It says the min. Iin occurs when Vin is…
Part Number: LM3492HC Tool/software: WEBENCH® Design Tools Hi There,
Do you have simulation tools for this part?
I tried WEBENCH but it showed it did not support this.
Kindly advice.
Thanks.
Part Number: LM3492HC Hi all Would you mind if we ask LM3492HC? There is the description "Current limit ICL= ICL(max) – 4290 × IILIM" on the datasheet P13.

Hello Ting, "(1000:1 at 3-kHz LED dimming frequency, minimum pulse width of the dimming signal is 300 ns)." However: "The lowest contrast ratio is 1000:1. The finest pulse width of the dimming signal for the DIM1 and DIM2 pins is 300 ns." I will check…
Part Number: LM3492HC As per the datasheet, 10Mega ohm pullup on the CDHC pin will disable the CDHC function.
In my design, I am planning to disable completely the CDHC function by providing a strong pullup. And configure the LM3492HC to a constant…
Other Parts Discussed in Thread: LM3492HC I would like to confirm the power good of LM3492HC.
In the datasheet, power good become high (COMM pin "H") when Vout ramp up.
If Vout degreases , does COMM pin change low?
If COMM pin changes, how much…
