Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'QPWPRQ1' matches the required package and tape-and-reel configuration. Confirm AEC-Q100 grade requirements align with your system's functional safety standards. Check component status as some variants may be marked Not Recommended for New Designs. Ensure ESD handling protocols are followed due to moisture sensitivity classification.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 2 A output current is necessary alongside a high input voltage tolerance up to 60 V. The adjustable frequency feature is critical if electromagnetic interference constraints require shifting the switching noise away from sensitive bands. Compare against the LM46000 series if lower current demands allow for reduced component size and cost.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the SIMPLE SWITCHER family, designed for compact power solutions. It shares architectural similarities with the LM46000 and LM46001 but offers higher current capacity. The Q1 suffix denotes automotive qualification, distinguishing it from commercial counterparts while maintaining pin compatibility within the broader LM4600x series.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM46002AQPWPRQ1 for updated symbolization or LM46002QPWPTQ1 for tape-and-reel variations. Verify thermal performance and external component values when migrating between these specific suffixes to ensure circuit stability.
