• LTC3119

    Hi,

    I am using LTC3119 as buck-boost converter. We have designed the circuit for VOUT=12V@2.5A. VIN=3-16V.

    The designed circuit is providing 12V at the above range without any issue. However, when I connect load(1A) and turn ON the PSU (which provides…

  • RE: LTC3119 oscillation at output

    Hi Massimiliano,

    It sounds like Vin is stable, but if you haven't I'd suggest verifying this with an oscilloscope.  You could bypass the PTC with a wire as a simple test.

    Are there any ceramic capacitors tied directly to Vout?  The eFUSEs add substantial…

  • LTC3119 compensation network example

    Hi everyone,

    I'm using the buck-boost converter LTC3119. In my project, it works with a input voltage from 3.3V to 14.8V. The output voltage and current are respectively 5.5V and 500mA. I choosed an external inductor of 10uH. I'm tring to design the external…

  • RE: NEED HELP WITH EDUCATIONAL BOOST CONVERTER

    Hi Aalt,

    For demo purposes of a boost converter (low input to high output voltage), you can make use of the evaluation boards that are readily available.  An example will be DC2129A LTC3119 Demo Board  found in link below.
