    RE: LMQ61460: Excessive ripple and dropout spikes with load current of 3.5A or greater.

    Hi Jim, Looks like you are operating at 24Vin|5Vout|440kHz. Based on the WEBENCH simulation schematic, this follows the TI datasheet recommendation and 3 x 47uF should be enough to keep the output ripple relatively low. Can you provide your PCB...

    RE: LMQ61460: Inductor saturation current

    Hi Danilo, Are you perhaps referring to Table 9-5 ? That 1.5uH MAPI inductor is used as an input filter to the LMQ61460. I don't expect the input current to get anywhere close to 6A for this to be of concern. The recommended output power inductor...

    RE: WEBENCH® Tools/LMQ61460-Q1: Minimum output voltage

    Hi Darren, I've contacted the internal team and previous apps engineer. As stated previously 1V output may be possible but will require significantly larger output capacitance. I'd suggest giving the customer a one of the LMQ61460EVMs to test...
