TPS55289RYQR Frequently Asked Questions (FAQs)

  • The maximum input voltage is 18V, but it's recommended to keep it below 15V for optimal performance and to prevent overheating.
  • To ensure stability, it's essential to use a minimum output capacitance of 10uF, and the output capacitor should be placed as close to the output pin as possible. Additionally, the input capacitor should be at least 1uF.
  • The maximum output current is 2A, but it's recommended to keep it below 1.5A for optimal performance and to prevent overheating.
  • The output voltage can be adjusted by using the FB (feedback) pin and an external resistor divider network. The FB pin is connected to the output voltage through a resistor divider, and the output voltage is set by the ratio of the resistors.
  • The EN pin is used to enable or disable the regulator. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled. This pin can be used to shut down the regulator when not in use to reduce power consumption.
