MC33262DR2G

Overview

The MC33262DR2G is a power factor correction (PFC) controller manufactured by onsemi, designed for high-efficiency AC-DC conversion systems. It operates within a supply voltage range of 12 V to 28 V and supports surface-mount installation in an 8-pin SOIC package measuring 5 x 4 x 1.5 mm. The device features a maximum operating temperature of +105 °C and a minimum of -40 °C. Key electrical characteristics include a start-up supply current of 0.4 mA, a maximum supply current of 12 mA, and peak source/sink currents of 500 mA.

Feature Summary

• Integrated zero-power detection capability for enhanced efficiency at light loads
• High-current drive outputs capable of sourcing and sinking up to 500 mA
• Operates reliably across extended industrial temperature ranges

Applications

• Power factor correction stages in AC-DC power supplies
• Industrial power conversion systems
• Consumer electronics requiring compliant power factors

Procurement Notes

Verify the specific suffix DR2G confirms the SOIC-8 surface mount package variant distinct from through-hole options. Confirm operational voltage requirements align with the 12 V to 28 V range. Ensure thermal management supports the +105 °C junction temperature limit. Cross-reference datasheet revisions for any pinout or functional updates prior to final design integration.

Selection Notes

Select this component when a dedicated PFC controller with high-drive capability is required for single-stage or two-stage topologies. The 500 mA output drive reduces external gate driver needs. Consider the 12 V minimum supply constraint against your bias circuit design. Evaluate the SOIC-8 footprint against available PCB real estate compared to alternative packages like PDIP.
