Description
The FAN7527B provides simple and high-performance
active Power Factor Correction (PFC). The FAN7527B
is optimized for electronic ballasts and lowpower, high-
density power supplies that require minimum board size,
reduced    external    components,    and    low    power
dissipation. Because the R/C filter is included in the
current-sense   block,   an   external   R/C   filter   is   not
necessary. Special circuitry prevents no-load runaway
conditions. Regardless of the supply voltage, the output
drive clamping circuit limits the overshoot of the power
MOSFET gate drive, which improves system reliability.
