ORDERING INFORMATION -
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. Internal Startup Timer One Quadrant Multiplier Zero Current Detector Trimmed 2% Internal Bandgap Reference Totem Pole Output Undervoltage Lockout with Hysteresis Low Startup and Operating Current Pinout Equivalent to the SG3561 Functional Equivalent to the TDA4817
