Application Specific Microcontrollers Procurement Notes

Verify that the specific part number corresponds to the pre-programmed variant intended for direct feedback designs. Confirm package details match the 24-pin QFN specification. Ensure firmware requirements align with the fixed configuration of the 'P' suffix model.

Application Specific Microcontrollers Selection Notes

Select this component for AC-to-DC adaptors requiring direct feedback topology rather than opto-coupler isolation. The pre-programmed nature suits designs needing minimal customization. Verify compatibility with external current-sensing resistors and VBUS load switch control signals.

Application Specific Microcontrollers Part Context

This part belongs to the EZ-PD™ CCG3PA-NFET portfolio, which provides BOM integration advantages by combining port control, regulation, and gate driving in a single chip. It serves as a specialized solution for compact power adapter designs.

Application Specific Microcontrollers Replacement Considerations

The CYPD3173-24LQXQ is the programmable counterpart within the same family. Substitution requires firmware development if the application demands customizable power profiles.
