UCC2817DTR

Overview

The UCC2817DTR is a Power Factor Correction (PFC) controller operating in average current mode. It supports switching frequencies from 6 kHz to 220 kHz and requires a supply voltage between 12 V and 17 V. The device features a 150 µA start-up current and is housed in a 16-SOIC surface-mount package. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Implements average current mode control for power factor correction applications
• Features programmable switching frequency capability up to 220 kHz
• Includes integrated zero-power detection functionality

Applications

• Average current mode PFC converters
• Universal AC input power supplies
• High-performance power factor correction stages

Procurement Notes

Verify the specific suffix 'DTR' indicates tape-and-reel packaging, distinct from the tube-packaged 'UCC2817D'. Confirm RoHS3 compliance status with the manufacturer prior to ordering. Ensure the design accommodates the specified 12 V to 17 V supply voltage range and SOIC-16 thermal requirements.

Selection Notes

Select this component for designs requiring average current mode PFC control with a maximum switching frequency of 220 kHz. It is suitable for applications needing a 16-pin SOIC footprint and operation within the -40°C to +85°C industrial temperature range. Verify compatibility with the required 12 V to 17 V supply voltage.

Part Context

The UCC2817 series consists of average current mode PFC controllers designed for high-performance power factor correction. The 'D' suffix denotes a 16-SOIC surface-mount package, while the 'TR' suffix specifies tape-and-reel packaging for automated assembly processes.

Replacement Considerations

The UCC2817AN is an obsolete through-hole alternative. For active replacements, consider the UCC28180DR, which offers CCM PFC control in an 8-pin SOIC package.
