UCC2817AN

Overview

The UCC2817AN is a discontinued Power Factor Correction (PFC) controller from Texas Instruments, designed for average current mode control. It operates within a switching frequency range of 6 kHz to 220 kHz and supports a supply voltage of 12 V to 17 V. The device features a 16-pin PDIP package with a standard 0.300-inch width. It includes an internal regulator and requires a startup current of 150 µA. The component is rated for operation between -40°C and +85°C.

Feature Summary

Implements average current mode control for power factor correction applications
Integrates an internal regulator to simplify external circuit design
Supports zero-power detection functionality

Applications

Power factor preregulators
AC-DC power supplies
Industrial power conversion systems

Procurement Notes

This component has reached End-of-Life status as of September 21, 2023. Availability is limited to existing stock or surplus channels. Verify the specific manufacturing date code and physical condition when sourcing from third-party distributors. Ensure that any replacement components meet the original electrical specifications and thermal requirements.

Selection Notes

Designers should consider the UCC2817DW or UCC2818AN as potential alternatives due to the discontinuation of the UCC2817AN. Evaluate pin compatibility and thermal performance when transitioning to surface-mount packages. Review the official datasheet for updated timing characteristics and ensure the selected substitute supports the required switching frequency range and current handling capabilities.

Part Context

The UCC2817AN belongs to the UCC2817 family of PFC controllers manufactured by Texas Instruments. This series utilizes BiCMOS technology to achieve high efficiency in power factor correction circuits. The analog variant distinguishes itself through its through-hole packaging and specific frequency control parameters suitable for legacy industrial designs.

Replacement Considerations

The UCC2818AN is listed as a manufacturer-recommended alternative. Verify functional equivalence regarding control topology and output drive strength before implementation.
