Nexperia AC/DC Controller ICs

Nexperia’s flyback controller portfolio combines quasi resonant and multi mode architectures to address diverse AC/DC power requirements. Quasi resonant devices enable high efficiency and low EMI through valley switching operation, while multi mode controllers optimize performance across wide load conditions to minimize standby power. Together, these solutions reduce system cost, improve power density, and enhance overall reliability for modern power supply designs.

Key features and benefits

• Quasi resonant (QR) and multi mode controller portfolio for diverse AC/DC design needs
• Wide VCC operating range for flexible bias supply design
• High efficiency across full load range, including optimized light load performance
• Low standby power consumption for energy-efficient designs
• Valley switching operation (QR) to reduce switching losses and improve EMI performance
• Adaptive multi mode control for improved light-load efficiency and transient performance
• Comprehensive protection features (OCP, OLP, OPP, SCP, OVP, OTP, UVLO, brown in/out and CS pin fault protection)
• Optimized BOM for cost-effective designs
• Stable and reliable operation across line and load conditions

Applications

• USB PD/QC chargers
• AC/DC adapters for portable devices
• Auxiliary power for industrial and home equipment
