  • RE: UCC27712: use UCC27712 high-side switch only

    Resolved
    Also, Zihao, I am confused by your statement, "...works on devices that don't have interlock" I don't think you are referring to UVLO, because the UCC27288 has UVLO as well.... I have an isolated DC-DC converter that can provide 800mA…

  • RE: UCC27712-Q1: Searching for a non-isolated half-bridge gate driver that does not have integrated diode

    Resolved
    Hello Yun, As Richard mentioned, there are several 600V half-bridge drivers that do not have the integrated diode from TI. Here are a couple of the 100V half-bridge drivers we have available at TI: UCC27288 and LM5109B-Q1. Best, Avery

  • RE: LM5108: Can bootstrap-intended half-bridge drivers be used with an external power supply rather than bootstrap capacitor ?

    Resolved
    Hi Ben, Thank you for reaching out! It sounds like you will want to implement charge pump circuitry to help keep the boot cap charged. TI has a tech article available that helps explain the process for implementing a charge pump: Link . I am unaware of…
