LTM4609MPY Frequently Asked Questions (FAQs)

  • The maximum output current of the LTM4609MPY is 9A per channel, but it can be paralleled to achieve higher output currents.
  • To optimize the layout, keep the input and output capacitors close to the device, use a solid ground plane, and keep the high-frequency switching nodes away from sensitive analog nodes. Also, use a shielded inductor and orient it to minimize radiation.
  • The recommended input capacitor type is a low-ESR ceramic capacitor, such as X5R or X7R, with a value of 10uF to 22uF. The capacitor should be placed close to the VIN pin to minimize inductance.
  • The output voltage of the LTM4609MPY can be set using a resistive divider network connected to the VOUT pin. The resistors should be chosen to provide a stable output voltage and to minimize the impact of output voltage ripple.
  • The thermal derating of the LTM4609MPY is typically 1.5°C/W above 25°C. This means that the maximum junction temperature of 125°C should be derated by 1.5°C for every degree above 25°C ambient temperature.
