  • LV2862: LV2862 heating up and going to thermal shutdown

    Resolved
    Part Number: LV2862 HI, We have made a custom board with LV2862 with 33uH inductor and DLFS1100 etc. We have device heating up badly and goes to thermal shut down. If we power the device with 24V (output is 12V) it works well but still heats to around…

  • LV2862: Optimizing buck converting efficiency and audible ringing for low load application

    TI Thinks Resolved
    Part Number: LV2862 Other Parts Discussed in Thread: LMR51603 Tool/software: Hi, I am using the LV2862 to convert nominal 36V to 12V with output loading varying from 1mA to 30mA. I followed the TI webench design for the LV2862. I noticed that when…

  • LV2862: LV2862 back feeding power, CB to SW rating

    TI Thinks Resolved
    Part Number: LV2862 I'm using an LV2862 to step down 22V to 3.3V, powering a MCU. During initial MCU programming, the 3.3V rail may be supplied by the programming jig, while the rest of the device is unpowered. This would back feed the LV2862 with…
