Promote energy-efficient and innovative ON Semiconductor (ON Semiconductor), launched a new device one pair of fully compliant with USB-C PD 3.0 standard. FAN6390 adaptive charging controller causes the USB-C PD 3.0 programmable power supply (PPS) standard easy to integrate into the system Copyright Control Engineering , and NCP12601 is a highly integrated multi-mode flyback controller, with strong performance in off-line power adapter. The new power device greatly simplifies the design of USB-C PD 3.0 based on CONTROL ENGINEERING China Copyright , provides a higher degree of integration and reliability, enabling higher power density designs, for a variety of application of electronic devices, such as smart phone charger, AC-DC power adapter and auxiliary power / internal power management.
ON Semiconductor continues its leadership in power management and USB-C PD program Control Engineering Copyright , and finally launched it’s first integrated synchronous rectifier and independent controllers, simplifying secondary end system design. ON Semiconductor FAN6390 is a USB-C PD 3.0 controllers integrated PPS of the first device. Scott Haddow ON Semiconductor senior director and general manager, said: “The need to have a larger capacity battery charging the same or faster time trend is accelerating USB-C PD of an integrated portfolio of compelling .FAN6390 implemented, will enhance the industry design and increase the power density of the travel adapter. “optimization of the structure provides operating mode based on the state machine to achieve all the functions required PD 3.0 and PPS function, which simplifies the design and manufacture of the final product. FAN6390 synchronous rectifier FET industry-leading drive technology to achieve high energy efficiency. Fine-tuning options set FAN6390 also provides flexibility and programmability for designers. Built-in high-resolution analog to digital converter 10 (DAC) fully compliant with USB-C PD 3.0 requirements, finely resolved PPS constant current / constant voltage (CC / CV) requirements. ON Semiconductor offers a thoroughly validated reference designs to help designers to further simplify integration. NCP12601 Add a variable frequency controller ON Semiconductor wide range of USB-C PD 3.0 line, which combines continuous current mode or multi-mode continuous current mode (CCM / DCM) and the bottom switch, to adapt to various load conditions. This method of control energy efficient than conventional fixed frequency pulse width modulation (PWM). Adding the bottom lock and proprietary silent skip cycle characteristics are significantly improved noise level to the market-leading, frequency jitter and provides improved electromagnetic interference (EMI) characteristics. To comply with USB-C PD 3.0 standard for designers can be a challenge, NCP12601 with unique auto-tuning and dual-stage over-current protection (OCP), to achieve the desired OCP function to meet the standards. Meanwhile, VCC bias low loss can be achieved wide output voltage range CONTROL ENGINEERING China Copyright without the need for additional external circuitry or complex transformer design. Adjustable slope compensation over power protection provided to ensure that after the addition of a single external resistor stable output power level regardless of operating input voltage. Other features include automatic restoration or protection compatible short pre-latch short-circuit protection, and a combination of dedicated pins or overtemperature protection on the CS pin using generic (OTP).
