    Alfred Croucamp
    I am investigating the benefits of using digital controllers. The one thing that looks promissing is mast of the devices have multiple PWM outputs and compensation loops. Are there any controllers that support multiple topologies? I would like to use a single controller to make the intermediate bus as...

    I have a design with two UCD9248 devices, controlling in total eight rails. All the rails uses UCD7242 drivers, in either single or dual phase configuration. The design works fine, with the exeption of Iout and Temp readings. No Iout reading reports any value below ~1.4 A, regardless of how small the...

    We just received a new assembly of our pcbs, and a UCD9248 design that previously worked does not. We're trying to determine if there was an assembly error or if we have bad/miscalibrated chips. The symptoms are that with the same circuit, our old board produces a V33A of 3.3V (using a circuit similar...
