Frequently Asked Questions
Q: Can both outputs operate simultaneously at full current?
A: Yes, the LTM4622EY#PBF supports dual 2.5A outputs operating independently with separate feedback loops.

Q: Is external compensation required?
A: No, all compensation components are integrated internally within the µModule® package.

Q: What thermal management is recommended?
A: The BGA package features an exposed pad for heatsinking. Use thermal vias to an inner plane for optimal θJA (thermal resistance specifications in datasheet).

Q: Does it require external MOSFETs?
A: No, power switches and drivers are fully integrated.

Q: How does the single 5A mode work?
A: Parallel both channels by connecting VOUT1 and VOUT2, with a single feedback loop from the combined output.

Q: Is this compatible with lead-free soldering?
A: Yes, the device is RoHS-compliant and rated for lead-free reflow profiles (see datasheet for details).
