FAN4800AS
Description
The highly integrated FAN4800AS/CS/01S/02S parts are specially designed for power supplies that consist of boost PFC and PWM. They require very few external ponents to achieve versatile protections / pensation. They are available in 16- pin DIP and SOP packages.
The PWM can be used in either current or voltage mode. In voltage mode, feed- forward from the PFC output bus can reduce the secondary output ripple. pared with older productions, ML4800 and FAN4800, FAN4800AS/CS/01S/02S have lower operation current that saves power consumption in external devices. FAN4800AS/CS/01S/02S have accurate 49.9% maximum duty of PWM that makes the hold- up time longer. Brownout protection and PFC soft- start functions available in this series are not available in ML4800 and FAN4800.
To evaluate FAN4800AS/CS/01S/02S for replacing existing FAN4800 and ML4800 boards, five things must be pleted before the fine- tuning procedure:
SOIC- 16 CASE 751BG
16 1
PDIP- 16 CASE 648- 08
