DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'N' confirms the PDIP-16 through-hole package variant. Confirm RoHS compliance status via the official datasheet. Ensure the supplier provides valid traceability documentation. Check for any recent process change notifications that may affect pinout or electrical characteristics. Validate that the component matches the original Texas Instruments manufacturing specifications.

DC DC Switching Controllers Selection Notes

Select this component when a through-hole solution is required for high-speed PWM control. It is suitable for designs needing up to 1 MHz switching frequencies. Consider the 2 A output drive capability for direct gate driving. Evaluate the -40°C to +85°C operating range against environmental requirements. Compare against surface-mount alternatives if board space is constrained.

DC DC Switching Controllers Part Context

This part belongs to the UC2823A series of high-speed PWM controllers from Texas Instruments. It is categorized under PMIC - Power Management ICs and specifically Switching Controllers. The device is distinct from the UC2823QTR which uses a PLCC package and has different electrical parameters like an 80% max duty cycle.

DC DC Switching Controllers Replacement Considerations

UC2823AN is a verified equivalent offering identical electrical specifications and PDIP-16 packaging. UC3823N serves as a commercial grade alternative with similar functionality but potentially different temperature ranges.
