LTM8047EY#PBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LTM8047EY can handle?
  The LTM8047EY can handle input voltages up to 40V, but it's recommended to operate within the specified input voltage range of 3.5V to 36V for optimal performance.
• How do I optimize the layout for the LTM8047EY to minimize EMI?
  To minimize EMI, it's recommended to follow a star-grounding scheme, keep the input and output capacitors close to the IC, and use a solid ground plane. Additionally, use a shielded inductor and keep the switching node (SW) away from sensitive nodes.
• What is the recommended output capacitor value and type for the LTM8047EY?
  The recommended output capacitor value is 10uF to 22uF, and it's recommended to use a low-ESR ceramic capacitor, such as an X5R or X7R type, to minimize output voltage ripple.
• How do I adjust the output voltage of the LTM8047EY?
  The output voltage of the LTM8047EY can be adjusted by using a resistive divider network between the output voltage and the FB pin. The recommended resistive divider ratio is 1:1 to 1:3.
• What is the maximum output current that the LTM8047EY can deliver?
  The LTM8047EY can deliver up to 4A of output current, but it's recommended to operate within the specified output current range of 0A to 3A for optimal performance.
