  • TPS25980: Startup glitch on TPS25980 simulation model

    Part Number: TPS25980 Hi, I am simulating the TPS25980 with pspice for TI and TI-provided model. I am seeing a glitch on the output while the TPS25980 is ramping up. I have come to the conclusion that it might be a simulation artifact, but wanted to…

  • TPS25980: TPS25980 hiccupping on startup with low capacitance load

    Part Number: TPS25980 Other Parts Discussed in Thread: TPA3116D2 We have a 24V DC supply that uses the TPS25980 to limit the output current to either 4A or 5A (selectable with a jumper). The circuit works as designed when using resistive loads or programmable…

  • TPS25980: Temp Range

    TI Thinks Resolved
    Part Number: TPS25980 Customer is using the TPS259802ONRGER and TPS259804ONRGER and found conflicting information in the datasheet regarding the operating temperature range, -15 to +125C and -40 to +125C. Could you confirm the correct operating temperature…

  • TPS25980: 24V/2A and 24V/4A EFUSE

    TI Thinks Resolved
    Part Number: TPS25980 Hi The customer needs eFuse solutions for both 24V/2A and 24V/4A applications. Could you please recommend suitable devices? We noticed that the TPS259807 does not provide OVP in a 24V application. Are there any other eFuse devices…
