MC33262 Power Factor Controller IC DIP 8 Package

MC33262 Power Factor Controller IC DIP 8 Package 

The MC33262 is a dedicated Power Factor Correction (PFC) controller IC designed for use in AC-DC power supply applications. It operates in critical conduction mode (CRM) or transition mode, shaping the input current to closely follow the input voltage waveform. This significantly improves power factor and reduces harmonic distortion, helping designs meet international power quality standards.

The IC integrates essential PFC functions such as a voltage error amplifier, multiplier, current sense comparator, and zero-current detection. With a low component count and reliable performance, the MC33262 is suitable for compact, cost-effective PFC solutions. The DIP-8 through-hole package makes it convenient for prototyping, educational use, and industrial power supply designs.
