Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix DRLR corresponds to the SOT-563 surface-mount package configuration. Confirm that the 16V maximum input rating aligns with your circuit design requirements rather than higher-rated variants. Ensure compatibility with standard reflow soldering profiles for this small outline transistor package type during assembly.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is required for moderate current applications up to 4A. The 1.2MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider thermal dissipation capabilities within the limited footprint of the SOT-563 package under full load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TPS56424x family of high-current synchronous buck converters. It shares architectural similarities with other members like the TPS56425x series but differs in input voltage limits and switching frequencies. The DRLR designation specifically identifies the reel-based packaging format for automated manufacturing processes.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

TPS564247DRLR offers similar functionality with a 17V input limit. TPS564252DRLR and TPS564255DRLR are parameter-equivalent alternatives within the same product family, providing options for different input voltage ranges or current capabilities.
