Hi, I have an IC on the side which is written” HVLED01A” on it and I want to know its output number. I wonder is equal to the” HVLED001A” output number or if it’s another IC? Thank you in advance.

    Thanks for your Question. For the IC, the turn-on voltage is between 11.5~12.9V, turn of is between 10.5~11.9V. So, for 12.15V, if the Vcc is from 12.9V down to it, the IC will run. If VCC is from 10V up to 12.15V, the IC is off and can't work.

Hii,

We’re using the below-mentioned IC in our design. While trying to flash the same using J Link Debugger Plus from Segger, the GUI of the tool asks to select the microcontroller from the drop-down list.
But Under the OEM, Infineon, the CYT2B7 series isn’t displayed. Hence we’re unable to select the target device from the GUI. Without selecting the target device, unable to proceed further with the flashing.

Hence I kindly request you to help me in this regard at the earliest.

We’re using the L6920 to drive a 1-watt LED.

We’re trying to apply the under voltage cut-off ( lockout) too. We chose the values of the voltage ground connected to the LBI pin similar that the value that comes to say 3V. Still, the IC didn’t shut off at 3V.
We also tried connecting the LBO to Vout with a 200K resistor in between. Even this didn’t work.

Can someone help apply this circuit?
Thanks!

    Well, the STLD40D is a boost converter. The function is also described in the data sheet, section5.1.

    It must be taken into account that the converter not only has a min off time, but also a maximum on time.
    The switch- on moment is particularly interesting firstly there’s no FB signal, so the power stage is switched on( SW to GND), which charges the boost inductor. As there isn’t yet enough affair voltage to drive a current through the LEDs, pin FB remains zero. still, the maximum on time now kicks in and switches the power stage off again, whereby the energy stored in the boost inductor is delivered to the LEDs at a high voltage and results in a corresponding current and a signal to FB. From now on, FB can regulate normally.

I’ve a design. I’ve 13 switch and these switches control to leds. For example when i click first button, first led will be on( likewise when i click again, it’ll be out). So microcontroller want to knows everything about it. But how can i control these leds? Because i want 36 * 3 io pins( RGB). Similarly after i want to control lightness of all leds with dimmer.

Do you have any IC hints for leds control & leds pwm controller?

    Of course, the correct type depends on several factors, e.g. how you want to control the LEDs( I2C, SPI, etc). With RGB LEDs you’ll clearly only switch one LED per channel, so you should be suitable to get by with one LED driver for 5V.

    Let me answer your questions 1.) The part number changes slightly depending if the OTP of the part is programmed or not. DA9062-XXAM1 is for parts on a tray AMC are parts in T&R. We have some standard variants like: - DA9062-0AAM1 for Qualcom Atlas 7 (On tray) - DA9062-11AM1 Avnet MiniZed boardRead more

    Let me answer your questions

    1.) The part number changes slightly depending if the OTP of the part is programmed or not.

    DA9062-XXAM1 is for parts on a tray AMC are parts in T&R.

    We have some standard variants like:

    – DA9062-0AAM1 for Qualcom Atlas 7 (On tray)

    – DA9062-11AM1 Avnet MiniZed board

    – DA9062-62AM1 i.MX6S Autoboot

    – DA9062-A0AM1 In Circuit Programming Variant (this is an empty unprogrammed part)

    Please note that the in case of an automotive option there is an additional -A at the end of the code. These parts will need to be programmed at factory to fulfill the AEC-Q100 etc requirements.

    2.) On the EV Kit there is a preprogram that has following outputs.Buck1 1.38V, Buck 2 1.5V, Buck3 3.3V and buck 4 1.8V, LDO1 3.3V, LDO2 1.8V,LDO3 3.0V and LDO4 2.8V.

    sequencing is slot1 LDO1, slot2 Buck1, slot3 Buck2, slot4 Buck3, slot5 Buck4, slot7 LDO 2 and 3, slot8 LDO4.Step time is set to 1,024ms.

    3.) There is a switch on the mother board that defines a mode we call Power Commander (PC mode). This mode prevents normal or programmed OTP register transfer to softregister, instead it writes the soft registers from the selected INI-file You can create yourself with the GUI and edit as you wish and save it. This will not be programmed to the OTP but it can be used for testing etc.

    4.) it is possible but one should be very careful and rememmber to turn on the power commander mode on, the switch. but you can do exactly pretty much the same with programmed part.
