Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official documentation, as variations may indicate differences in tape-and-reel specifications or environmental compliance status. Confirm that the requested part number matches the exact pinout and thermal pad configuration required for the target PCB layout. Cross-reference the manufacturer's latest datasheet revision to ensure compatibility with current manufacturing standards and material declarations.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single-phase solution is sufficient for loads up to 12 A. The fixed 600 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Ensure the application requires an adjustable output voltage within the specified 0.6 V to 12 V range and can accommodate the thermal dissipation characteristics of the PQFN-15 package under maximum load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This regulator belongs to the SupIRBuck series, which integrates power switches to reduce footprint. It serves as a monolithic alternative to discrete buck converter designs, simplifying board layout and improving transient response. The PQFN-EP-15 package facilitates efficient heat transfer through the exposed thermal pad to the underlying copper plane.
