Power Factor Controllers
The MC34262/MC33262 are active power factor controllers specifically
designed for use as a preconverter in electronic ballast and in off鈥搇ine power
converter applications. These integrated circuits feature an internal startup
timer for stand鈥揳lone applications, a one quadrant multiplier for near unity
power factor, zero current detector to ensure critical conduction operation,
transconductance error amplifier, quickstart circuit for enhanced startup,
trimmed internal bandgap reference, current sensing comparator, and a
totem pole output ideally suited for driving a power MOSFET.
Also included are protective features consisting of an overvoltage
comparator to eliminate runaway output voltage due to load removal, input
undervoltage lockout with hysteresis, cycle鈥揵y鈥揷ycle current limiting,
multiplier output clamp that limits maximum peak switch current, an RS latch
for single pulse metering, and a drive output high state clamp for MOSFET
gate protection. These devices are available in dual鈥搃n鈥搇ine and surface
mount plastic packages.
