ON Semiconductor has released a pair of novel devices that are compliant with the USB-C PD 3.0 standard. The FAN6390 adaptive charging controller delivers ease of integration of the USB-C PD 3.0 PPS standard into systems whilst the NCP12601 is a highly integrated multi-mode flyback controller for high-performance, rugged, offline power supplies such as adapters. The new devices considerably simplify USB-C PD 3.0 based power supply designs, offer higher-level integration and reliability, and facilitate higher power density design for applications including smartphone chargers, AC/DC power adapters and auxiliary/housekeeping power supplies for multiple electronic devices.
The FAN6390 is the first in a family of USB-C PD 3.0 with PPS controllers to be provided by the company. “The trend of higher capacity batteries requiring the same or faster charging times is accelerating the adoption of USB-C PD. The family of FAN6390 products enables an impressive level of integration which will enhance industrial design and improve power density for travel adapters,” states Scott Haddow, senior director and general manager. The optimised architecture offers state machine-based operation for all features needed for PD 3.0 and PPS functionality provding ease of end product design and manufacturing. The device produces high efficiency via industry-leading synchronous rectifier FET driving techniques. The device can also offer designers with flexibility and programmability through trim optioning.
Adding further to the company’s extensive USB-C PD 3.0 portfolio is the NCP12601 variable frequency controller that consolidates multi-mode continuous current mode or discontinuous current mode (CCM/DCM) operation with valley switching to accommodate an extensive assortment of load conditions. This approach offers superior efficiency when compared to conventional fixed-frequency PWM controllers. The addition of valley lockout and a proprietary quiet skip feature improve the noise performance significantly to market-leading levels whilst frequency jitter offers an enhanced EMI signature.
