Procurement Notes

Verify the specific suffix 'BN' against official Texas Instruments documentation to confirm the PDIP-16 through-hole package and commercial temperature range specifications. Ensure that ordering requirements align with the manufacturer's standard packaging definitions rather than distributor-specific quantities. Cross-reference the part number with the latest datasheet to validate all electrical parameters before procurement.

Selection Notes

Select this component when a through-hole solution for power factor correction is required. The UC2854BN provides average current mode control suitable for applications needing sinusoidal input current shaping. Consider the 16-pin PDIP package constraints and the specified operating temperature limits during thermal design. Verify compatibility with the target switching frequency requirements of the system.
