LTM4620IY Frequently Asked Questions (FAQs)

  • The LTM4620IY can drive up to 10nF of capacitive load, but it's recommended to limit it to 4.7nF for optimal performance and stability.
  • To minimize EMI and noise, it's recommended to follow a star-ground configuration, keep the input and output traces short and away from each other, and use a solid ground plane. Additionally, place the input and output capacitors close to the device and use a common-mode choke if necessary.
  • The recommended input voltage range for the LTM4620IY is 2.9V to 5.5V, but it can operate down to 2.7V with reduced performance. It's not recommended to operate the device below 2.7V or above 5.5V.
  • To select the right output inductor, consider the output voltage, output current, and switching frequency. A good starting point is to use an inductor with an inductance value between 1uH to 10uH, and a current rating that exceeds the maximum output current. Additionally, consider the inductor's DC resistance, core material, and physical size.
  • The thermal derating curve for the LTM4620IY is not explicitly stated in the datasheet, but it can be estimated based on the device's thermal resistance and maximum junction temperature. As a general rule, the device's output current should be derated by 1% for every 1°C increase in temperature above 25°C.
