Highly-Integrated Green-Mode PWM Controller
FAN6755W / FAN6755UW — mWSaver™ Controller June 2011 FAN6755W / FAN6755UW ™ mWSaver PWM Controller Features Description ™ This highly integrated PWM controller provides several mWSaver Technology Provides Industry’s Best-in- features to enhance the performance of flyback Class Standby Power converters. o <100mW at 25mW Load for LCDM Adaptor To minimize standby power consumption, a proprietary o Internal High-Voltage JFET Startup adaptive green-mode function reduces switching o Low Operating Current Maximum: 2mA frequency at light-load condition. To avoid acoustic- o Adaptive Decreasing of PWM Frequency to noise problems, the minimum PWM frequency is set 23KHz at Light-Load Condition, Improved above 23kHz. This green-mode function enables the Light-Load Efficiency power supply to meet international power conservation ® requirements, such as Energy Star . With the internal o Feedback Impedance Switching During high-voltage startup circuitry, the power loss caused by Minimum Load or No Load bleeding resistors is also eliminated. To further reduce Proprietary Asynchronous Frequency Hopping power consumption, FAN6755W/UW uses the BiCMOS Reduced EMI process, which allows an operating current of only 2mA. The standby power consumption can be under 100mW Fixed PWM Frequency: 65KHz (FAN6755W), 130KHz (FAN6755UW) for most of LCD monitor power supply designs. Internal Leading-Edge Blanking FAN6755W/UW integrates a frequency-hopping function that reduces EMI emission of a power supply with Built-in Synchronized Slope Compensation minimum line filters. Its built-in synchronized slope Auto-Restart Protection: Feedback Open-Loop compensation achieves a stable peak-current-mode control and improves noise immunity. The proprietary, Protection (OLP), V Over-Voltage Protection DD (OVP), Over-Temperature Protection (OTP), and external line compensation ensures constant output Line Over-Voltage Protection power limit over a wide AC input voltage range from 90V to 264V . AC AC Soft Gate Drive with Clamped Output Voltage: 18V FAN6755W/UW provides many protection functions. V Under-Voltage Lockout (UVLO) DD The internal feedback open-loop protection circuit Programmable Constant Power Limit (Full AC protects the power supply from open feedback loop Input Range) condition or output short condition. It also has line under-voltage protection (brownout protection) and over- Internal OTP Sensor with Hysteresis voltage protection using an input voltage sensing pin Build-in 5ms Soft-Start Function (V ). IN Input Voltage Sensing (V Pin) for Brown-In/Out IN FAN6755W/UW is available in a 7-pin SOP package.
