    Hello Jamie, TLD509xEP are LED DC-DC controller...

    Hello Jamie,
    TLD509xEP are LED DC-DC controller and as you mentioned you can use them as voltage regulator as well.
    To use these devices into voltage mode power supply you have to change the...
  2. What are the key differences between TLD5095, TLD5097 and TLD5098?

    The TLD509x mainly differ in maximum output voltage, output current accuracy, analog dimming, short-to-ground protection and capability to drive an external NMOS for dimming purpose from each other: ...
  3. How to adjust output current according to LED temperature and binning of a DC-DC LED?

    Our LITIX boost controllers like TLD5099EP have two options to dim the output current without a microcontroller:
    - Analog current adjustment
    - Embedded PWM engine

    In the system these two options...
  4. What are the key features of the TLD5099EP?

    The key features of TLD5099EP are:


    Embedded spread spectrum modulator to dither the switching frequency
    Embedded PWM engine
    NMOS gate driver for dimming purpose
    4KV ESD protection on...
  5. Can the pin VSET of LITIX boost controllers be directly connected to the 12V battery

    Yes, the VSET pin can be directly connected to the 12V battery line - the maximum voltage rating of this pin is 45 V.

    Please check the LITIX Power webpage.
  6. Do the boost converter LED drivers in the LITIX Power family have a fault signal?

    TLD5097EP is having a dedicated status pin ST.

    TLD5098EP and TLD5099EP indicate faults via the PWMO pin. It will be set to low level in case of an error.

    See...
  7. As you mentioned, the TLD5099EP is a controller,...

    As you mentioned, the TLD5099EP is a controller, then the power limit is not related to the device, but mainly to the topology used.
    Asynchronous DC-DCs have good performances up to 50-60 W. Above...
  8. Hello Yebing, nice to see you again in this...

    Hello Yebing,

    nice to see you again in this forum with a nice thread...

    For the DC-DC you have to play with some digital gates to build-up a solution to implement N-1 function.
    Here I used as...
  9. TLD6098-1EP differs from TLD5099EP for the...

    TLD6098-1EP differs from TLD5099EP for the following key points:

    5466

    Please check frequently our LITIX Power webpage and LITIX Power Flex webpage to have more information on the new products.
  10. Here in the below picture I also highlight the...

    Here in the below picture I also highlight the main difference on the produced waveforms of output current and voltage.
    5465
    As reported in the previous reply, the main advantage using the PWMO...
  11. For an LED driver the difference is on the...

    For an LED driver the difference is on the waveform of the output current.
    Using PWMO connected to and NMOS the system is able to produce very sharp current waveform at output, while if the PWMO is...
  12. Hello Robert, to dim the LED current you have...

    Hello Robert,

    to dim the LED current you have to change the voltage on the SET pin.
    To do that, a resistor divider from IVCC is the good choice.
    the first idea that came to my mind is to use...
  13. Hi Jacky, nice to meet you in this forum. ...

    Hi Jacky,

    nice to meet you in this forum.

    The dimming ratio (called also contrast ratio) is the ratio between the PWM period and the minimum duty time manageable by the DC-DC.

    In order to...
