Description
The MC34262 is a high-performance Active Power Factor Controller (PFC) IC specifically designed to meet the increasing requirements for power factor correction in AC-DC power supply applications. By forcing the input current to track the sinusoidal shape of the AC line voltage, this controller helps achieve a near-unity power factor and significantly reduces harmonic distortion.
Operating in Critical Conduction Mode (CRM), the MC34262 offers high efficiency and simplified design, making it an excellent choice for Switch-Mode Power Supplies (SMPS) and electronic ballasts. It incorporates essential features like an internal startup circuit, precise reference voltage, and robust protection circuitry to ensure stability under varying load conditions.
