NEX82016 is a highly integrated and high-performance digital-analog hybrid LLC controller. It operates in multi-mode conditions, and works together with the dual channel SR controller NEX81915/6 to achieve an efficient and reliable power supply. This makes NEX82016 suitable for medium to high power isolated power supply applications.
NEX82016 has been optimized to simplify the overall design and maximize LLC performance. Advanced multiple mode control allows for independent configuration of the working status of each mode. Skip mode during light load reduces the switching loss. Adjustable dead time reduces conduction loss. Burst mode control and ultra-low static current maximize the ultra-light load efficiency and reduce standby power consumption. Efficiency can be improved across the entire load range.
NEX82016 adopts a current mode control architecture with good loop stability. Open register configuration allows for flexible configuration of various control and protection parameters, with a few peripheral components and easy design. It integrates a half-bridge drive module, capable of directly driving LLC bridge MOSFETs. In addition, NEX82016 has built-in high-voltage start-up function and X-cap discharge function, effectively simplifying peripheral components and reducing the total BOM cost of the power supply.
Features and benefits
Integrates high-voltage start-up and X-cap discharge functions, with simple peripheral circuits
Integrates a half-bridge driver, supporting a maximum frequency of 600 kHz
High-performance digital-analog hybrid control
Flexible configuration of various control and protection parameters
Ultra high efficiency across the entire load range
Out of audible noises at all operating modes
Brown-in/brown-out protection
Overcurrent protection (OCP)
Overpower protection (OPP)
Capacitive Mode Regulation (CMR)
Short-circuit protection (SCP)
Overvoltage protection (OVP)
Internal and external overtemperature protection (OTP)
Available in SO16 package
Applications
Desktop and laptop adapters
TV and monitor power supplies
LED drivers
AC-DC power sources
