DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'DWR' corresponds to the SOIC-16 surface mount package and reel packaging configuration. Confirm RoHS compliance status through official documentation. Ensure moisture sensitivity level handling protocols are followed during assembly. Cross-reference the manufacturer part number against current datasheets to validate active status and pinout compatibility before integration into production designs.

DC DC Switching Controllers Selection Notes

Select this controller when application requirements demand high switching frequencies up to 1 MHz to minimize passive component size. Choose this part if the design utilizes single-output topologies like Boost or Flyback. Consider this component for environments requiring extended temperature operation up to 105°C. Evaluate the 1.5 A drive capability against gate charge requirements of the external power switches to ensure adequate performance without additional buffering.
