Procurement Notes
Verify component authenticity through authorized onsemi distributors or certified partners. Confirm RoHS compliance status and manufacturing date codes prior to integration. Ensure storage conditions adhere to moisture sensitivity level requirements. Validate that the specific package variant matches design footprint specifications. Review latest datasheet revisions for any pinout or electrical characteristic updates before finalizing procurement orders.
Selection Notes
Select this regulator when a compact solution with 1.5A capacity and 520kHz operation is required. Consider the 4.5V to 40V input range compatibility with system power rails. Evaluate thermal dissipation needs given the 150°C junction rating. Compare against alternative family members if different switching frequencies or output configurations are necessary for specific noise or size constraints.
Part Context
This part belongs to the CS5141x series of low-voltage buck regulators from onsemi. The series offers various switching frequencies and current ratings tailored for diverse power management needs. The CS51414 variant specifically provides a 520kHz frequency option, balancing size and efficiency.
