Procurement Notes

Verify the specific suffix PHTR indicates reel packaging when ordering. Confirm the HTSSOP16 package type matches your PCB footprint requirements. Ensure compatibility with the 4.5 V to 61 V input range for your specific power supply design. Check RoHS compliance status if required by your manufacturing standards. Validate thermal management solutions given the exposed pad package for heat dissipation.

Selection Notes

Select this component for designs needing up to 3 A continuous current from a single channel. Consider the adjustable frequency range for optimizing external inductor size. Evaluate the low dropout operation for applications with minimal voltage headroom. The integrated protection features against overcurrent and thermal shutdown simplify system safety design without additional external circuitry.
