Applications
General-purpose switched-mode power supplies and flyback power converters, including:
● LCD Monitor Power Supply
● Open-Frame SMPS
Description
This highly integrated PWM controller provides several features to enhance the performance of flyback converters.
To minimize standby power consumption, a proprietary adaptive green-mode function reduces switching frequency at light-load condition. To avoid acoustic-noise problems, the minimum PWM frequency is set above 23kHz. This green-mode function enables the power supply to meet international power conservation requirements,such as Energy Star. With the internal high-voltage startup circuitry, the power loss caused by bleeding resistors is also eliminated. To further reduce power consumption, FAN6755W/UW uses the BiCMOS process, which allows an operating current of only 2mA.The standby power consumption can be under 100mW for most of LCD monitor power supply designs.
FAN6755W/UW integrates a frequency-hopping function that reduces EMI emission of a power supply with minimum line filters. The built-in synchronized slope compensation achieves a stable peak-current-mode controland improves noise immunity. The proprietary line compensation ensures constant output power limit over a wide AC input voltage range from 90VACto 264VAC.
FAN6755W/UW provides many protection functions. The internal feedback open-loop protection circuit protects the power supply from open-feedback-loop condition or output-short condition. It also has line under-voltage protection (brownout protection) and over-voltage protection using an input voltage sensing pin (VIN).
FAN6755W/UW is available in a 7-pinSOP package.
