HA16174FP-E

Overview

The HA16174FP-E is a Power Factor Correction (PFC) control IC designed for digital television applications. It integrates functions to ensure high reliability, including continuous conduction mode operation suitable for systems with frequent current changes. The device supports ON/OFF control of the main converter and load via a PG signal and includes a hold function against AC temporary blackouts. Additional features include over-voltage protection with feedback loop absence detection, quick soft-start, and improved load regulation through a Gm amplifier.

Feature Summary

• Integrates continuous conduction mode control for stable operation during rapid current changes
• Provides hold function capability to maintain system state during AC temporary blackouts
• Includes over-voltage protection with specific feedback loop absence detecting function
• Utilizes a Gm amplifier to enhance load regulation performance

Applications

• Digital TV power supply systems
• Power Factor Correction units requiring stabilization
• Systems needing protection against AC temporary blackouts

Procurement Notes

Verify the exact suffix designation, as datasheets list HA16174FP and HA16174P. Confirm if the -E suffix denotes a specific environmental compliance or packaging variant distinct from standard listings. Cross-reference with Renesas official documentation to ensure the component matches the intended PFC controller specifications for digital TV applications before procurement.

Selection Notes

Select this IC for digital TV designs requiring integrated PFC control with blackout hold capabilities. It is suitable for systems needing continuous conduction mode stability and over-voltage protection with feedback loop monitoring. Consider its integration of Gm amplifiers for load regulation needs in compact power supply architectures.
