MC34262 Power Factor Controller IC DIP 8 Package

MC34262 Power Factor Controller IC DIP 8 Package 

The MC34262 is a dedicated Power Factor Correction (PFC) controller IC designed to improve the power factor and reduce harmonic distortion in AC-DC power supply applications. It is typically used in critical conduction mode (CRM) or transition mode boost PFC converters to shape the input current so it closely follows the input voltage waveform.

The IC integrates essential PFC control functions including a voltage error amplifier, current sense comparator, multiplier, and zero-current detection circuitry. With minimal external components and reliable performance, the MC34262 is well suited for compact and cost-effective PFC designs. The DIP-8 through-hole package makes it ideal for prototyping, education, and industrial power supply designs.
