  • TPS65910: Use a power-on delay circuit to slow down the rise of VDDIO.

    Part Number: TPS65910 Tool/software: Hi, This is a continuation of the previous question. Please refer to the related threads before reading this post. I took measures to slow down the rise of VDDIO using a power-on delay circuit (CR time constant circuit…

  • TPS65910: "SWIO" fails to start

    Part Number: TPS65910 Other Parts Discussed in Thread: AM3352 Tool/software: I asked the same question before, but it was locked so I started a new question. ----Previous question--------- When powering up, the "SWIO" voltage may not be output about once…

  • TPS65910: "SWIO" fails to start

    Part Number: TPS65910 Other Parts Discussed in Thread: AM3352 Tool/software: Due to issues encountered with the previous thread, we have created a new one. We apologize for the delay in setting up this new thread. ----Previous question--------- When powering…

  • TPS65910: "SWIO" fails to start

    Part Number: TPS65910 Other Parts Discussed in Thread: AM3352 Tool/software: When powering up, the "SWIO" voltage may not be output about once in 1000 times. I am using a combination of AM3352BZCZ80 and TPS65910A31A1RSLR. Is there anything that…

  • AM3352: Configuring TPS65910 RTC in AM3352 Device Tree

    Other Parts Discussed in Thread: TPS65910 , AM3352 Currently, I'm using the AM3352 platform and the TPS65910 PMIC for development. I want to automatically load the tps65910-rtc driver during system boot. During the boot process, I encountered the following…

  • RE: TPS65910: VRTC_LDO voltage fluctuation (Please help ASAP)

    Hi Yuki, When you are driving the SLEEP pin, could you try using a rising and/or falling edge to try and drive this behaviour instead of perhaps starting at a constant level? Have/Could you try writing a '0' to the DEVCTRL_REG 0x3F bit 1 while ensuring…

  • TPS65910: Change the VMMC slew rate by the register

    TI Thinks Resolved
    Part Number: TPS65910 Hi, We are using TPS65910AA1RSL(R) as the power supply for DP83826IRHBR. From the thread below, if the rising voltage of VDDIO is less than 0.5ms, an ESD protection event will occur, It is mentioned that large currents may be consumed…

  • TPS65910: Efficiency and Thermal estimator

    Part Number: TPS65910 Hi Is there any efficiency and thermal estimator tool for TPS65910 PMIC? or is there any graph available for efficiency vs load current for BUCKs and LDOs?

  • TPS65910: How to set TPS65910A3 PMIC to let Vout enter PWM mode?

    Part Number: TPS65910 Hi Expert, How to set TPS65910A3 PMIC to let Vout enter PWM mode? The customer tried to register address as 0x20 and 8bits data as 01000001, but could not enter PWM mode. Thanks Daniel

  • TPS65910: SWIO output capacitor

    Resolved
    Part Number: TPS65910 Hi support team, This is a question about TPS65910A31A1RSLT. 14pin: At SWIO output +1.5V, supply destination device (CPU, DDR3 SDRAM) input conditions (MAX side: 1.575V) were found to be just at the limit. A 10uF bypass capacitor…
