Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix (e.g., NOPB) against official Texas Instruments documentation to confirm RoHS compliance and package details. Confirm availability status as distribution channels may list discontinued or limited stock items. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target application design.

Power Supply Controllers, Monitors Selection Notes

Select this component for applications requiring secondary-side regulation with a wide input voltage range. Consider the 16-TSSOP package for space-constrained designs. Evaluate the 50 kHz to 1 MHz frequency range against EMI requirements and external component sizing needs. Verify that the 2.5 A output current capability aligns with the load requirements.

Power Supply Controllers, Monitors Part Context
