MC33261 Datasheet POWER FACTOR CONTROLLERS

Manufacturer: Motorola Semiconductor (now NXP Semiconductors)

Overview

Order this document by MC34261/D 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.
