ON Semiconductor MC33262CDR2G Power Factor Correction Controller

The MC33262CDR2G is a highly efficient power factor correction (PFC) controller designed by ON Semiconductor, a leader in energy-efficient innovations. This integrated circuit is tailored for use in low to medium power applications requiring power factor correction, such as offline power supplies and electronic ballasts. The device is particularly well-suited for systems that must comply with international power factor regulations, ensuring that energy consumption is optimized for both environmental and cost-saving benefits.

This PFC controller operates in the critical conduction mode, also known as the boundary mode, which allows for zero current switching at turn-off, reducing switching losses and improving overall efficiency. The MC33262CDR2G is designed to provide a near-unity power factor by shaping the input current waveform to match the line voltage waveform, thereby minimizing the reactive power component.

The device comes in an 8-pin SOIC package, which is compact and suitable for space-constrained applications. Its operating temperature range is from -40°C to +105°C, making it reliable in various environmental conditions. The MC33262CDR2G features a low startup current and a low operating supply current, which contributes to its energy-saving capabilities.

Key features of the MC33262CDR2G include an internally trimmed bandgap reference, a fixed-frequency oscillator with on-chip frequency jittering for lower EMI, cycle-by-cycle current limiting, and overvoltage protection. These features enhance the safety, reliability, and performance of the end application. Additionally, the device has a built-in undervoltage lockout with hysteresis and a totem pole output, which is capable of directly driving a power MOSFET.

The MC33262CDR2G is an excellent choice for designers looking to improve the energy efficiency of their power supply designs while reducing the size and cost of passive components. Its advanced features and robust design ensure compliance with global energy standards, making it a preferred component for environmentally conscious and cost-effective power management solutions.
