Single-Chip PWM Solution Saves Board Space
Designers who need to achieve lower standby power consumption in devices
such as notebooks, printers, LCD TVs, now have an industry-leading single-chip
solution with Fairchild’s FAN6756. Lower standby power in 75W space-
constrained applications is achieved without additional external circuitry, complex
designs or higher costs. The single-chip solution is a highly integrated green-
mode 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.
