LTM8051IY Frequently Asked Questions (FAQs)

  • The maximum output current of the LTM8051IY is 1A per channel, with a total maximum output current of 2A for both channels.
  • To minimize EMI, it is recommended to follow a star-ground configuration, keep the input and output traces separate, and use a solid ground plane. Additionally, placing the input capacitors close to the device and using a shielded inductor can help reduce EMI.
  • The recommended input capacitor value is 10uF to 22uF, and it should be a low-ESR ceramic capacitor, such as X5R or X7R, to ensure stable operation and minimize noise.
  • The LTM8051IY is rated for operation up to 125°C, but it is recommended to derate the output current and input voltage at high temperatures to ensure reliable operation. Consult the datasheet for specific derating guidelines.
  • The LTM8051IY has a SYNC pin that can be used to synchronize the switching frequency with an external clock. The SYNC pin should be driven with a clock signal that is within the specified frequency range (200kHz to 400kHz) and has a duty cycle of 50% ± 10%.
