SLVSEL7B April 2019 – October 2019 TPS61390
The output voltage of the TPS61390 is externally adjustable using a resistor divider network. The relationship between the output voltage and the resistor divider is given by Equation 5.
Choose RDOWN to be approximately 10 kΩ. Slightly increasing or decreasing RDOWN can result in closer output voltage matching when using standard value resistors. In this design, RDOWN = 10 kΩ and RUP = 487 kΩ, resulting in an output voltage of 60 V.
