  • TPS25990EVM: Why use diode between Vout and GND?

    TI Thinks Resolved
    Part Number: TPS25990EVM Other Parts Discussed in Thread: TPS25990 Hi In the TPS25990 EVm, the SBR10U45SP5 (SUPER BARRIER RESTIMP) is connected between the VOUT and the gnd. What is the purpose of your use? Thanks

  • TPS25990EVM: UV_FLT after the switch turns off, the output voltage does not immediately return when the input voltage recovers to undervoltage threshold + 0.25V

    Part Number: TPS25990EVM Other Parts Discussed in Thread: TPS25990 Tool/software: When using the TPS25990 to set UV_FLT , after the switch turns off because the input voltage falls below the undervoltage threshold (UV_FLT), the output voltage…

  • TPS25990EVM: Cannot connect to EVM through USB2GPIO

    Part Number: TPS25990EVM Hello, I am trying to setup this EVM for a customer, but I am unable to connect. I open the GUI, follow the hardware setup instructions but when the GUI starts scanning for devices no addresses are found. I am unsure of the…

  • TPS25985: Efuse shut off tSU_TMR after enable efuse using PMBus command

    TI Thinks Resolved
    Part Number: TPS25985 Other Parts Discussed in Thread: TPS25990 , TPS25990EVM We are using TI's TPS25990+TPS25985 and encounter problems during validation. After initial power on, we issued PMBus command to disable, then enable the efuse ( TPS25990…

  • RE: TPS25990: Can't connect to the device through cloud agent. Fusion Designer now stops working after Cloud agent installed

    Hi Jun, We tested TPS40400EVM-351 with TPS25990EVM by connecting the SCL and SDA lines of the respective EVM's together. Using a single USB-TO-GPIO2 USB interface adapter evaluation module, my PC can interact with both GUIs, Fusion GUI and TPS25990…

  • RE: TPS25990: Inquiries regarding TPS25990 operation

    Are you using TPS25990EVM? If yes, this EVM consists of TPS25900 and TPS25985 in parallel. GPIO3 must be set to SWEN. GPIO2 or GPIO4 should be used as a comparator output. GPIO_CONFIG_12 (E1h, Read/Write Byte) and GPIO_CONFIG_34 (E2h, Read/Write Byte…

  • RE: TPS25990: Hot short circuit problem

    Please see the below waveforms. The UVLO protection was completely disabled in the TPS25990 by two ways: EN/UVLO pin is connected to VIN through a 1 MΩ resistance. A 1 μF ceramic capacitor is connected across the EN/UVLO pin and GND. This helps in…

  • RE: TPS25990: TPS25990+TPS25985

    Mor Gedalya said: What value should I set for VRTH(V)? 0V, Mor Gedalya said: When I power up with a 15V input with a load resistor 0.15ohm. The TPS25985 reports a fault and pulls the SWEN signal low. So small resistance during start-up can't be…
