Lower standby power in 75W spaceconstrained applications is achieved without additional external circuitry, complex designs or higher costs. The single-chip solution is a highly integrated greenmode PWM controller that significantly reduces standby losses in SMPS designs, and eliminates up to 15 external components. The FAN6756 also includes an innovative AX-CAP™ discharge method that minimizes losses in the EMI filter stage, while meeting the IEC61010-1 safety requirement. This functionaity is achieved by eliminating the X-cap discharge resistors and discharging X-cap energy through the HV pin when the power is unplugged from the AC outlet. Ideal for power supplies that demand extremely low standby power, the FAN6756 incorporates mWSaver™ Technology. This technology allows the device to reduce power losses not only in the controller, but also in the external circuits and components. It also includes a proprietary deep burst mode technology that reduces switching loss at no-load and light-load conditions.

OptoHiT™ PHOTOTRANSISTOR OPTOCOUPLERS Advantages • Excellent CTR linearity at high temperature • CTR at very low input current, IF (1mA, 1.6mA, and 3mA) • Small footprint: half-pitch mini-flat package (MFP) saves board real estate for more flexibility and overall systems cost savings Reliable Isolation and Minimized System Failure with OptoHiT™ Optocouplers Realize increased design margins and stable parameters in high temperature environments with Fairchild’s new FODM8801 OptoHiT™ high temperature phototransistor optocoupler. You’ll achieve high noise immunity and reliable isolation at high operating temperatures, up to 125°C, as this new series implements Fairchild’s proprietary OPTOPLANAR® coplanar packaging technology. In addition, the FODM8801 offers excellent CTR linearity and operates at a very low input current (IF). The optocoupler consists of an aluminum gallium arsenide (AlGaAs) infrared light emitting diode optically coupled to a phototransistor. Because the FODM8801 is packaged in a compact, half-pitch, mini-flat, 4-pin package (1.27mm lead pitch), benefits also include board space savings and design flexibility, ultimately allowing for overall reductions in system cost.

Because the need to work reliably in a small space while providing high efficiency is imperative, the device uses a digital technique that allows it to automatically detect the AC input voltage condition. A special internal reference signal is then created, resulting in high power factor correction. The FL7701 will work from a DC input voltage condition, automatically sensing AC versus DC input voltage conditions. It also combines high functional density to create the smallest form factor and allows designers to save up to 20% BOM costs and up to 60% board space savings. The LED driver provides energy savings that meet the most stringent worldwide regulations, such as Energy Star®. Designers also benefit from the high degree of integration offered by the FL7701. The result is increased luminary lifespan to more than five years (current solution only achieves three years.) And reliability is also improved since no electrolytic capacitors for the input, output or the FL7701 VDD supply are required.
