MC34261, MC33261

Power Factor Controllers

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.
