Voltage Regulators - DC DC Switching Regulators Procurement Notes
Verify the specific suffix YJL-TR against the official datasheet to confirm the 28-PowerVQFN package and tape-and-reel packing media. Ensure the required input voltage does not exceed 19V and the load current remains within the 12A limit. Confirm thermal management requirements for operation up to 125°C junction temperature.
Voltage Regulators - DC DC Switching Regulators Selection Notes
Select this component when a compact solution is needed for converting higher voltages down to low-voltage logic or processor rails. The 600kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the application requires a single positive output channel and fits within the specified input window.
Voltage Regulators - DC DC Switching Regulators Part Context
This part belongs to the MIC24055 family of high-efficiency buck regulators. It is distinct from other Microchip power ICs by its specific 12A current rating and 19V maximum input specification. The YJL-TR designation indicates the specific package type and reel quantity configuration.
Voltage Regulators - DC DC Switching Regulators Replacement Considerations
Consult official substitution guides for compatible parts with similar input ranges and current capabilities. Direct replacements must match the 28-PowerVQFN footprint if board space is constrained.
