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.

ORDERING INFORMATION

KK34262N Plastic

KK34262D SOIC

T_A= 0° to 85° C for all packages.

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.

• Overvoltage Comparator Eliminates Runaway
