Other Parts Discussed in Thread: TPS65910

If the power management TPS65910A31A1RSL of the AM335X is changed to 5V input, is there any risk? Currently our application is 3.6V input, I want to change to 5V input.

Or is there any other power management recommendation for 5V input?

    Meng jeffrey,

    According to the datasheet, the maximum recommended input voltage for the TPS65910 is 5.5V for the main power rail pins: VCC1, VCC2, VCCIO, VCC3, VCC4, VCC5, VCC6, VCC7.

    The following digital input pins are also rated up to 5.5V: PWRON, PWRHOLD, GPIO_CKSYNC

    Pins that are not rated up to 5.5V are referenced to a lower voltage and should not be affected by the new 5V input. For example, I2C pins (SCL and SDA) are referenced to VDDIO and BOOT0/1 are referenced to VRTC.

    I do not see any risk with your input voltage moving from 3.6V to 5V, as long as your application does not violate the Recommended Operating Conditions of the TPS65910 device.

    Thanks & Best Regards,

    Brian
