To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild_questions@onsemi.com.

Description

The highly in tegrated FAN4800AU/CU parts are specially designed for power supplies that consist of boost PFC and PWM. They require very few external components to achieve versatile protections and compensation. They are available in 16 -pin DIP and SOP packages. The PWM can be used in current or Voltage Mode. In Voltage Mode, feed -forward from the PFC output bus can reduce secondary output ripple. To evaluate FAN4800AU/CU for replacing existing FAN4800A/C, FAN4800AS/CS, old version FAN4800 and ML4800 board s, six things must be completed before the fine-tuning procedure: 1. Change RAC resistor from the old value to a higher resistor value: 6 M to 8 M. 2. Change RT/CT pin from the exi sting value s to RT=6.8 k and C T=1000 pF to have fPFC=64 kHz and fPWM=64 kHz. 3. The VRMS pin needs to be 1.224 V at V IN=85 VAC for universal input application with line input from 85 VAC to 270 VAC. 4. Change ISENSE pin filter from the exiting values to RFilter=51  and CFilter=0.01 µF for higher bandwidth. 5. At full load, the average V VEA must be ~4.5 V and ripple on VVEA needs to be less than 400 mV. 6. For the SS pin, the soft -start current has been reduced to half the FAN4800 capacitor. There are two differences from FAN4800AS/CS to FAN4800AU/CU:  Add Line Sagging Protection  Fix Inductance Current Instability during AC Cycle Drop Test
