Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'Q1' confirms automotive grade status against the official datasheet. Confirm the 'PWP' package code matches the required HTSSOP-16 footprint for PCB design compatibility. Check the latest manufacturer notices for any lifecycle changes, as availability may vary by region. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing for automotive applications requiring wide input voltage tolerance up to 60 V. It is suitable for designs needing a single adjustable output with moderate current demands around 1 A. Consider the thermal performance within the 16-HTSSOP package for the expected ambient conditions. Compare against non-automotive equivalents if cost is critical but automotive certification is not mandatory.
