SLVSDG7A April 2016 – April 2021 TPS54202H
PRODUCTION DATA
The output voltage of the TPS54202H device is externally adjustable using a resistor divider network. In the application circuit of , this divider network is comprised of R2 and R3. Use Equation 6 and Equation 7 to calculate the relationship of the output voltage to the resistor divider.
Select a value of R2 to be approximately 100 kΩ. Slightly increasing or decreasing R3 can result in closer output voltage matching when using standard value resistors. In this design, R2 = 100 kΩ and R3 = 13.3 kΩ which results in a 5-V output voltage. The 49.9-Ω resistor, R1, is provided as a convenient location to break the control loop for stability testing.
