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. Its built-in synchronized slope compensation achieves a stable peak-current-mode control and improves noise immunity. The proprietary, external line compensation ensures constant output power limit over a wide AC input voltage range from 90VAC to 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-pin SOP package.
