What is the recommended pulldown resistor value for the TPS65050 PB_IN input?

    I would propose a resistor of 10k to 1M at PB_IN.  This is a digital input and the input leakage current of PB_IN is typically less than 100nA so the value of the resistor is not critical.  A lower resistor value will make the circuit more noise resistant so 10kohm is the best choice.  Because current only flows through the resitor when the push button switch is being pushed, you do not need to worry about power consumption when using a lower resistor value.
