Nexperia’s advanced AC/DC controller ICs are optimized for today's high-performance, energy-efficient power conversion requirements.
As smartphones and connected devices continue to advance, power demands are growing faster than battery capacity improvements—often forcing multiple charges per day. Fast chargers help users recharge quickly, but to protect battery life and device longevity, high-quality, efficient power supplies are essential.
Nexperia’s dedicated AC/DC controller ICs deliver lower standby power, higher conversion efficiency, greater power density, and enhanced reliability. These solutions are ideal for USB Power Delivery (PD) chargers, adapters, and industrial power supplies.
Nexperia’s portfolio includes:
- NEX806xx quasi-resonant flyback controllers
- NEX808xx multi-mode flyback controllers
- NEX8180x synchronous rectifier controllers
Combined with power discretes, these form a complete flyback solution, perfect for smartphone chargers, e-bike battery chargers, and power tools.
Typical charger / adapter for smartphones and other low power devices
Key features for efficient and reliable industrial power conversion:
- High efficiency via valley switching and Pulse Frequency Modulation (PFM) reduces losses and standby power.
- Wide input voltage range (10–83 V) supports unstable industrial power sources.
- Peak power mode handles surges up to twice the output power without compromising stability—critical for motors and solenoids.
- Robust protection features like overvoltage (OVP) and overcurrent protection (OCP) safeguard sensitive systems.
- Integrated MOSFET or GaN HEMT driving reduces design complexity and Bill of Materials (BOM).
- Spread spectrum technology minimizes electromagnetic interference (EMI), helping meet industrial standards.
Isolation and safety in high voltage applications
As high-voltage applications grow, galvanic isolation is essential to separate low-voltage control circuits from high-voltage power, ensuring user safety and system reliability. Typically used after the main DC output (e.g., 24 V), the NXF650x generates isolated 5 V or 3.3 V rails for control and communication circuits, crucial in industrial environments. Nexperia is expanding its analog portfolio, including power management, isolation, interface, and voltage translation.
