UCC28517DWR

Overview

The UCC28517DWR is an advanced Power Factor Correction (PFC) and Pulse Width Modulation (PWM) combination controller manufactured by Texas Instruments. It integrates a peak current-mode PFC controller with a PWM post-regulator in a single package to simplify power supply design. The device operates within a supply voltage range of 10.8 V to 15 V, with a nominal input of 12 V. It is housed in a 20-pin SOIC package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Integrates peak current-mode PFC control with a dedicated PWM post-regulator for combined power factor correction and output regulation.
• Utilizes current-mode control technology to manage power conversion processes efficiently.
• Designed as a complete solution for power factor correction applications requiring post-regulation capabilities.

Applications

• Power supplies requiring integrated PFC and PWM control
• Advanced power factor correction systems
• Post-regulated power conversion circuits

Procurement Notes

Verify the specific suffix 'DWR' corresponds to the tape-and-reel packaging variant when ordering. Confirm that the 20-SOIC package dimensions align with your PCB footprint requirements. Ensure the -40°C to +105°C operating temperature range meets your environmental specifications. Cross-reference the datasheet revision date to ensure compatibility with your design constraints.

Selection Notes

Select this component when a single-chip solution for both power factor correction and voltage regulation is required. It is suitable for designs aiming to reduce component count by combining PFC and PWM functions. Consider the 20-pin SOIC package size for board space limitations. Verify that the 10.8 V to 15 V supply range fits your auxiliary power architecture.

Part Context

This part belongs to the UCC28517 family of advanced PFC/PWM combination controllers from Texas Instruments. It shares functional similarities with other devices in the series designed for high-efficiency power conversion. The DWR suffix indicates the reel-packaged version of the standard DW SOIC-20 device.
