UCD3138 Power Factor Correction Firmware
UCD3138FW-PFC
Overview
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.
Features
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)
