SINGLE-CHIP PWM SOLUTION

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.

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.
