Fairchild Semiconductor has introduced a range of AC regulators which are designed to achieve less than 0.5W power consumption in standby mode.
This means the devices can be used in systems designed to meet the power saving requirements of the 2013 EU eco-design directive ErP (Energy-related Products) Lot 6.
This requires the maximum power consumption of electronic devices in standby mode to be less than 0.5W in applications such as PCs, game consoles and LED TVs.
The FSB series integrates current-mode pulse width modulator (PWM) and an avalanche-rugged 700V SenseFET in a single package.
The design incorporates technology to minimises losses in the EMI filter stage by eliminating the X-cap discharge resistors while still meeting IEC61010-1 safety requirements.
There is a green-mode function which provides off-time modulation, which linearly decreases the switching frequency at light-load condition to minimise switching losses.
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.
