The MC34261/MC33261 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, a one quadrant multiplier for near unity power factor, zero current

detector to ensure critical conduction operation, high gain error amplifier,

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 input undervoltage

lockout with hysteresis, cycle–by–cycle current limiting, and a latch for single

pulse metering. These devices are available in dual–in–line and surface

mount plastic packages.
