Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix CSDE corresponds to the WSON-10 package configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure the ordering part number matches the required tape and reel or cut tape packaging format specified for your assembly line requirements.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for designs requiring a compact step-down solution with high input voltage tolerance up to 50 V. The fixed 1 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 1.25 A current limit when sizing output inductors and capacitors to maintain desired ripple specifications and thermal performance within the operating temperature range.
