LTC3850EUF#TRPBF Frequently Asked Questions (FAQs)

  • The maximum operating temperature range for the LTC3850EUF is -40°C to 125°C.
  • To ensure stability, a minimum output capacitance of 10uF with an ESR of 1Ω or less is recommended. Additionally, the output voltage should be decoupled with a 10nF ceramic capacitor.
  • The maximum input voltage that the LTC3850EUF can handle is 28V. Exceeding this voltage may cause damage to the device.
  • The switching frequency of the LTC3850EUF can be programmed by connecting a resistor (RT) from the RT pin to GND. The switching frequency is inversely proportional to the value of RT.
  • The SYNC pin allows the user to synchronize the switching frequency of the LTC3850EUF with an external clock signal. This can be useful in reducing electromagnetic interference (EMI) in systems with multiple switching regulators.
