SAN JOSE, Calif. – October 3, 2011 – The power saving requirements of the 2013 EU eco-design directive ErP (Energy-related Products) Lot 6 requires the maximum power consumption of electronic devices in standby mode to be less than 0.5W. This requirement remains a significant challenge for auxiliary power supply designs in applications such as PCs, game consoles and LED TVs.

Fairchild Semiconductor (NYSE: FCS), a leading global supplier of high-performance power and mobile products, introduced the FSB series of AC regulators, the next-generation green-mode Fairchild Power Switch (FPS™) to help designers meet the challenge of achieving less than 0.5W power consumption in standby mode. By incorporating Fairchild's mWSaverTM technology, devices in the FSB series dramatically reduce standby and no-load power consumption, enabling conformance to all worldwide standby mode guidelines.

The FSB series integrates advanced current-mode pulse width modulator (PWM) and an avalanche-rugged 700V SenseFET in a single package solution allowing auxiliary power designs with higher standby energy efficiency, reduced size, improved reliability and a lower system cost than previous solutions.

An innovative AX-CAP™ method, one of the five proprietary mWSaver technologies, minimizes losses in the EMI filter stage by eliminating the X-cap discharge resistors while still meeting IEC61010-1 safety requirements. mWSaver technology's green-mode function provides off-time modulation, which linearly decreases the switching frequency at light-load condition to minimize switching losses. Combined with the extremely low operating current, the FSB series easily meets and exceeds the light load power consumption limits.

Integrated protection features include programmable cycle-by-cycle current limiting, internal open-loop protection, built-in brown-in and brown-out protection, high and low line compensation for constant power limit, over-temperature protection with hysteresis, under-voltage lockout and over-voltage protection. The FSB-series offers integrated MOSFETs with different current ratings to cover up to 35W designs. The first product released in the lineup is the FSB127H with 2A internal MOSFET. It is available in an 8-pin dual-inline package.

Fairchild Semiconductor's mWSaver technology offers best-in-class minimum no-load and light-load power consumption to meet current and proposed worldwide standards and regulations and enables designs with reduced footprint, improved reliability, and lower system cost.
