FAN4800A SMD SOP16

توضیحات

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 capacitors, 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 requirements improve efficiency and reduce

component costs.
