LTM4644EY#PBF Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LTM4644EY is 15V, but it's recommended to operate within the specified input voltage range of 2.9V to 14V for optimal performance.

  • To minimize EMI, it's recommended to follow good PCB layout practices such as keeping the input and output traces short and away from each other, using a solid ground plane, and placing the input and output capacitors close to the device.

  • The recommended output capacitor value for the LTM4644EY is 10uF to 22uF, with a low ESR (Equivalent Series Resistance) to ensure stability and optimal performance.

  • The LTM4644EY is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation.

  • The LTM4644EY has built-in overcurrent protection and thermal shutdown, but it's recommended to add external protection such as fuses or PTC resistors to prevent damage from excessive current or temperature.
