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.
