Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix YD6 corresponds to the TSOT-23-6 thin package variant when sourcing. Confirm RoHS compliance status as per the latest manufacturer documentation, noting potential changes from Micrel to Microchip transitions. Ensure the ordering part number matches the required tape and reel quantity specifications for your assembly line requirements.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is needed for boosting low input voltages to higher levels efficiently. The 1.2MHz frequency allows for smaller external passive components compared to lower frequency alternatives. Consider the 350mA current limit and 35V maximum output voltage when designing circuits that require moderate power conversion in space-constrained environments.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MIC2619 family of boost converters designed for high-voltage, low-power applications. The 'TR' suffix indicates it is supplied in a tape and reel format suitable for automated surface-mount assembly processes. The device represents a transition from Micrel products now managed under Microchip Technology's portfolio.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for direct pin-compatible substitutes within the MIC2619 series or other Microchip boost converters with similar 1.2MHz frequencies and TSOT-23-6 packaging. Verify that any replacement maintains the same input/output voltage ranges and current capabilities before integration.
