Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix PWPT indicates cut-tape or reel packaging configuration when ordering. Confirm that the component meets RoHS compliance standards required by your assembly process. Ensure the HTSSOP-16 footprint matches your PCB layout constraints. Check for any recent product change notices regarding symbolization or assembly sourcing updates before finalizing procurement plans.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part for applications needing a compact solution with wide input voltage tolerance. The adjustable frequency feature helps minimize external component size. Consider the 500mA limit for load requirements. The PowerTSSOP package offers thermal performance suitable for moderate power densities. Verify compatibility with existing system clocking if external sync is utilized.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM4600x series of SIMPLE SWITCHER regulators. It shares architectural similarities with automotive-grade variants like the LM46000AQPWPTQ1 but lacks AEC-Q100 qualification. The PWPT designation specifically denotes the surface-mount package type and tape-and-reel or cut-tape availability format used for automated assembly processes.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM46000PWP serves as the tube-packaged equivalent. LM46000PWPR is the standard reel version. For automotive applications, consider LM46000AQPWPTQ1. Higher current options include LM46001QPWPRQ1 (1A) and LM46002AQPWPRQ1 (2A). All share similar pinouts and control interfaces.
