DC DC Switching Controllers Procurement Notes

Verify the specific ordering suffix 'PWR' against the manufacturer's official documentation to confirm the tape and reel packaging format. Ensure the part number matches the exact revision required for your design, as obsolete status may affect long-term availability. Cross-reference the datasheet version to validate all electrical parameters before integration.

DC DC Switching Controllers Selection Notes

Select this controller for designs requiring active clamp reset topologies in flyback or forward configurations. It is suitable for applications needing isolated outputs with precise current-mode control. Consider the 16-TSSOP package constraints and the 6.6V to 18V supply range when defining the bias circuitry requirements for the power stage.
