UCD3138FW-PFC

UCD3138 Power Factor Correction (PFC) firmware gets a designer through evaluation to production in power supply designs based on a PFC topology by providing all-inclusive firmware that can integrate easily with your housekeeping functionality.

This firmware comes with native support for following features:

• Innovative ZVS/Valley Switching Algorithm to boost light load efficiency and reduce THD
• Integrated cycle by cycle protection provides protection for over voltage, over current, brownout, power-on inrush current
• Easily re-configurable to dual-phase interleaved PFC or Bridgeless PFC
• Integrated power metering capability eliminates dedicated power metering chip
• 8X oversampling and innovative ZVS/valley switching improve light load efficiency & THD
• EMI x-cap compensation to help simplify your system design.
• Fast AC drop detection
• Non-Linear digital control
• Automatic current balancing for interleaved PFC
• Current harmonic reduction by selective injection
• Special burst mode improves efficiency
• Duty ratio feed forward control
• Dynamic loop compensation

 What’s Included:

• Board support packages (BSPs)
• User Guides
