Description

The

highly

integrated

FAN4800A/C

and

FAN4801/1S/2/2L 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, FAN4800A/C and FAN4801/1S/2/2L have

lower operation current that save power consumption in

external devices. FAN4800A/C and FAN4801/1S/2/2L

have accurate 49.9% maximum duty of PWM that

makes the hold-up time longer. Specifically, the

brownout protection and PFC soft-start functions are not

in ML4800 and FAN4800.

To start evaluating FAN4800A/C, FAN4801/1S/2/2L for

replacing existing FAN4800 and ML4800 boards, five

things must be done 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,

PWM

=64KHz.

VRMS pin needs to be 1.224V at V

=85 V

for

universal input application from line input from

85V

to 270 V

. Both poles for the V

rms

FAN4801/1S/2/2L don’t need to substantially

slower than FAN4800; about 5 to 10 times.

At full load, the average V

needs to ~4.5V and

the ripple on the V

needs to be less than 400mV.

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

reduced to half from 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

Distributed Power
