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

components to achieve versatile protections /

compensation. 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.

Compared 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 completed before the fine-tuning procedure:

Change R

resister from the old value to a higher

resister: between 6MΩ to 8MΩ.

Change RT/CT pin from the existing values to

=6.8kΩ and C

=1000pF to have f

PFC

=64kHz and

PWM

=64kHz.

The VRMS pin needs to be 1.224V at V

=85 V

for universal input application from line input from

85V

to 270V

At full load, the average V

VEA

needs to be ~4.5V

and the ripple of V

VEA

needs to be less than

400mV.

For the Soft-Start pin, the soft-start current has

been reduced to half the FAN4800 capacitor.

Applications

Desktop PC Power Supply

Internet Server Power Supply

LCD TV, Monitor Power Supply

UPS

Battery Charger

DC Motor Power Supply

Monitor Power Supply

Telecom System Power Supply
