FAN4800  
Low Start-Up Current PFC/PWM Controller Combos  
Features  
Description  
„ Low start-up current (100µA typical)  
„ Low operating current (2.5mA typical)  
„ Low total harmonic distortion, high power factor  
„ Pin-compatible upgrade for the ML4800  
The FAN4800 is a controller for power-factor-corrected,  
switched-mode power supplies. Power Factor Correction  
(PFC) allows the use of smaller, lower-cost bulk capaci-  
tors, reduces power line loading and stress on the  
switching FETs, and results in a power supply that fully  
complies with IEC-1000-3-2 specifications. Intended as a  
BiCMOS version of the industry-standard ML4800, the  
FAN4800 includes circuits for the implementation of  
leading edge, average current, boost-type power factor  
correction, and a trailing-edge Pulse Width Modulator  
(PWM). A gate driver with 1A capabilities minimizes the  
need for external driver circuits. Low-power require-  
ments improve efficiency and reduce component costs.  
„ Average current, continuous or discontinuous boost,  
leading-edge PFC  
„ Slew rate enhanced transconductance error amplifier  
for ultra-fast PFC response  
„ Internally synchronized leading edge PFC and trailing-  
edge PWM  
„ Reduction of ripple current in the storage capacitor  
between the PFC and PWM sections  
„ PWM configurable for current-mode or voltage-mode  
An over-voltage comparator shuts down the PFC section  
in the event of a sudden decrease in load. The PFC sec-  
tion also includes peak current limiting and input voltage  
brownout protection. The PWM section can be operated  
in current or voltage mode, at up to 250kHz, and  
includes an accurate 50% duty cycle limit to prevent  
transformer saturation.  
operation  
„ Additional folded-back current limit for PWM section  
„ 20V BiCMOS process  
„ VIN OK guaranteed turn-on PWM at 2.25V  
„ VCC OVP comparator, low-power detect comparator  
„ Current-fed gain modulator for improved noise  
The FAN4800 includes a folded-back current limit for the  
PWM section to provide short-circuit protection.  
immunity  
„ Brownout control, over-voltage protection, UVLO,  
soft-start, and reference OK
