I am using step down converter
TPS62056 from texas instrument
(http://focus.ti.com/lit/ds/symlink/tps62056.pdf)
I'd like to use one switch connect to Vin and EN pin with pull down resistor to ground.
can someone help me to determine the value of pull down resistor
because the typ input currentof En pin is 2 uA (page 3), is that means i have to use big resistor?
also the example in datasheet (page 12) use big resistor if I use 2 switches, do i have to use same value if I only use 1 switch?
