• LT8612 - Switching noise interference

    We use lt8612 36V to 12V  as the first stage  power supply for ad9681. The configuration is shown in the figure. The 12V output is normal.

    However, 1MHz burr appears in ad9681. It is found that the switching frequency of lt8612 is 1MHz, and the burr is…

  • LT8612 Current Limit

    We have a 5V Step-Down Converter configured as shown on the front page of the data sheet.  Input voltage is 20 VDC.

    If the 5V output is shorted to ground, how much input current will there be from the 20 VDC input?

  • LT8612 - Switch on Problems

    Hello,

    I have a problem with the LT8612 in the following circuit.

    In the simulation with LT-Spice everything works as planned.
    I wanted to use the EN/UV pin to switch on the -15V supply.
    In the real circuit, the controller only starts when I generate a…

  • LT8612 Iout max

    Vin = 33v

    Vout = 24v

    What is Iout max ?

    Is it 6A?

  • [LT8612] Question about EN/UV

    To whom may it concern, 

    I'm HS.

    According to the datasheet of LT8612, the device will be ON when EN/UV is applied with HIGH and shutdwon when it's connected to GND.

    But the datasheet doesn't explain how LT8612 will work when this EN/UV Pin is…

  • LT8612

    Hi

     

    I have a question LT8612


    I am seeing the standard application of the 5 V (3.3 V) step-down converter on page 18 of the data sheet.

    · Product number: LT 8612
    · Question: How can I set SYNC (1 pin) / PG (23 pin)?
    · Usage form: 28V-38Vin ⇒ 5Vout, 28V…

  • LT8612 Loop stability in inverting buck boost configuration

    Hello,

    I plan to use the LT8612 in inverting buck-boost (IBB) configuration to generate Vout = -15V from Vin = +5V.

    Is there a possibility to check loop stability? Or is this not needed as the internal compensation is always stable?

    Looking forward to…

  • RE: LTC7801 Current Sensing Complexity

    Hi Chris,

    The first option for current sensing sounds more sensible to me. If you can find a buck with IMON pin like LT8612/LT8613, that monitoring pin would be useful.

  • RE: LT3045 Constant Voltage Output Mode

    Hi Oriol,

    Do you mean you want to do a variable power supply? You may want to check this as reference. DC2132A, 24V 3A Constant Voltage, Constant Current Bench Supply Featuring LT3081, LT8612, LT3092
