Designers of consumer electronics under 40W – such as adapters, set top boxes, netbooks, and digital photo frames – all need an energy efficient solution that provides <100mW standby power in order to meet worldwide energy saving requirements. To meet this challenge, Fairchild Semiconductor has developed the FAN6863, a highly integrated PWM controller that offers lower standby power and higher efficiency.

The device is suited to space constrained designs and offers high surge protection for increased reliability.

It minimises standby power consumption by using a proprietary green-mode function that has off-time modulation to continuously decrease the switching frequency under light-load conditions.

Under zero-load conditions, the power supply enters burst-mode, which shuts off the PWM output. This technology allows the device to achieve standby power of: <100mW at no-load conditions, which enables designers to meet international power consumption requirements.

The controller is packaged in a small form factor SSOT-6, is ideal for space constrained designs while offering functionality normally found in some of the larger device packages.

It provides large gate driving capability – 400mA for up to 40W applications, surge capability up to 7KV for higher reliability, as well as an integrated internal frequency hopping function, which helps reduce EMI emissions with minimal line filters.

The controller supports the technology to offer designers improved integration, efficiency and packaging options that result in increased performance and reliability for better device design and end application functionality for users.
