Power Factor Controllers

The MC34262/MC33262 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, 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−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.
