IVCC1104EDR

Overview

The IVCC1104EDR is a CCM Totem-Pole PFC controller by Inventchip, designed for high-efficiency power conversion. It operates with a supply voltage of 4.75V to 5.25V and supports an operating temperature range of -40°C to 125°C. The device utilizes average current mode control with input voltage feedforward to enhance dynamic response and reduce total harmonic distortion. It features automatic anti-backflow protection during AC dropout and optimized zero-crossing control for smooth current transitions. The component is available in a 16-pin SOIC package.

Feature Summary

• Implements average current mode control with input voltage feedforward for rapid current tracking
• Provides automatic anti-current backflow protection upon AC input dropout
• Optimizes AC zero-crossing control to minimize current spikes and improve waveform quality
• Supports both SiC and GaN devices without requiring programming or digital debugging

Applications

• Server power supplies
• Compact PFC power modules
• High-power mobile phone and laptop chargers
• Avionics power systems

Procurement Notes

Verify the specific suffix 'EDR' against the manufacturer's official datasheet to confirm pinout compatibility and package type (SOIC-16). Ensure that the ordering documentation explicitly lists this part number as active. Cross-reference the RoHS status and moisture sensitivity level with the latest production batch data before procurement.

Selection Notes

Select this component for applications requiring high power density and efficiency in the 300W to 4000W range. It is suitable for designs utilizing either resistive or Hall-effect current sensing. Consider its analog nature if digital programmability is not required. Verify that the system can accommodate the specified 4.75V to 5.25V supply voltage and thermal requirements up to 125°C.

Part Context

The IVCC1104EDR belongs to the IVCC110x series of analog Totem-Pole PFC controllers from Inventchip. This series is engineered to simplify power supply development by integrating precise control circuits directly into compact packages. The EDR variant specifically denotes the 16-pin SOIC packaging option, distinguishing it from other form factors like QFN within the same functional family.
