MC33262DR2G

The MC33262DR2G from ON Semiconductor is an active power factor controller designed for use as a preconverter in electronic ballast and off-line power converter applications. This integrated circuit is housed in an 8-SOIC package and supports a surface mount type.

Key features include an internal startup timer, a one-quadrant multiplier for near unity power factor, and a zero current detector for critical conduction operation. It also incorporates a transconductance error amplifier, quickstart circuit, trimmed internal bandgap reference, current sensing comparator, and a totem pole output suitable for driving a power MOSFET.

Protective features consist of an overvoltage comparator, input undervoltage lockout with hysteresis, cycle-by-cycle current limiting, multiplier output clamp, an RS latch for single pulse metering, and a drive output high state clamp for MOSFET gate protection. The device operates within a voltage range of 12V to 28V and an operating temperature range of -40°C to 105°C. It also features a low startup and operating current, with a typical operating current of 250 µA.

This device supersedes the functionality of the SG3561 and TDA4817. It is available in an 8-SOIC package with a width of 0.154 inches (3.90mm). The MC33262DR2G is designed for applications requiring efficient power factor correction.
