TECHNICAL DATA
Power Factor Controllers
The are active power factor controllers specifically
designed for use as a preconverter in electronic ballast and in
off-line power converter applications.
These integrated circuits feature an internal startup timer
for stand-alone applications, a one quadrant multiplier for near
unity power factor, zero current detector to ensure critical
conduction operation, transconductance error amplifier, quick
start 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-by-cycle 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-in-line and surface mount plastic packages.
