Less than 40 W consumer electronic products such as laptop computers, set-top box, the Internet and digital photo frames) design personnel, face the same challenges, is to provide a standby power consumption less than 100 mW of highly energy-efficient solution to satisfy the world energy conservation regulations.

In response to this challenge, a leading global supplier of high performance and portable power Fairchild Fairchild Semiconductor company () developed a high level of integration FAN6863 PWM controller, in small package size, can provide more low standby power consumption and higher efficiency.

FAN6863 devices using proprietary green model function to provide cut-off time modulation, can be in light load conditions, thus reducing switch frequency for maximum reduce standby power consumption. In the zero load conditions, the power supply into the intermittent operation mode to shut off the PWM output, FAN6863 device adopt this technology to realize through without load conditions of less than 100 mW standby power consumption, can make good design personnel meet international energy consumption regulations.

FAN6863 by small appearance SSOT-6 encapsulation, apply to the space is limited, and can provide the design in the functionality of the device larger package. This device has a large enough gate drive current capacity of 400 mA, suitable for the application within 40 W, up to seven KV resistance to surge capacity achieve higher reliability, but also has integrated type internal shaking frequency function to help reduce EMI radiation and minimize line filter.

FAN6863 device is fairchild comprehensive product series, part of the can help design personnel deal with engineering technical challenges, through providing technology, level of integration, efficiency and packaging options for its design, bring higher performance and possibility.
