LTM8045MPY#PBF - Analog Devices

Description: The LTM®8045 is a µModule® (micromodule) DC/DC converter that can be configured as a SEPIC or inverting converter by simply grounding the appropriate output rail. In a SEPIC configuration the regulated output voltage can be above, belowor equaltothe input voltage. TheLTM8045 includes power devices, inductors, control circuitry and passive components. All that is needed to complete the design are input and output capacitors, and small resistors to set the output voltage and switching frequency. Other

LTM8045MPY#PBF Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. The device's thermal pad should be connected to the ground plane using multiple thermal vias.
  • Ensure that the input voltage rises monotonically and does not droop during start-up. A soft-start circuit can be used to control the input voltage rise time.
  • The maximum allowed capacitance on the output is 100uF. Exceeding this value may cause instability or oscillations.
  • Yes, but the inductor value should be chosen to ensure that the inductor current ripple is within the recommended range (20-40% of the maximum output current).
  • Check the PCB layout for noise coupling, ensure that the input and output capacitors are properly decoupled, and verify that the inductor is properly sized and shielded.
