IVCC1102DR

Overview

The IVCC1102DR is a continuous conduction mode (CCM)图腾柱PFC controller manufactured by Zhiyin Electronics. It replaces traditional diode rectifier bridges with four MOSFETs for synchronous rectification and PFC boosting, eliminating diode forward voltage drop losses. The device supports 5V input supply with undervoltage lockout and features two synchronous rectification drive outputs and two high-frequency PFC drive outputs. It utilizes optimized AC current zero-crossing smooth control and fixed feedforward ratio technology to generate accurate PWM signals, preventing reverse current during AC power loss. The chip offers adjustable switching frequency and configurable dead time.

Feature Summary

• Eliminates diode forward voltage drop losses by replacing traditional rectifier bridges with synchronous MOSFET control
• Prevents AC reverse current through fast response PWM adjustment using patented input voltage feedforward control
• Achieves smooth AC zero-crossing current via optimized control techniques that reduce current spikes and ripple
• Provides comprehensive protection including output overvoltage, AC over/under voltage, and peak current limiting

Applications

• Server power supplies
• Compact PFC power modules
• Television and gaming console power supplies
• High-power laptop and mobile phone chargers
• Aviation electronic power systems

Procurement Notes

Verify the manufacturer designation as Zhiyin Electronics rather than Inventchip, as official documentation attributes the IVCC1102 series to this entity. Confirm the specific suffix DR corresponds to the SOIC-16L or QFN-20L package variants listed in the datasheet. Ensure compatibility with SiC or GaN devices if utilizing the synchronous rectification features. Validate that the application environment supports the specified 5V input supply and undervoltage lockout requirements.
