ROHM Semiconductor USA, LLC Power Factor Correction BD7694FJ-E2

The BD7694FJ-E2 is a Power Factor Correction (PFC) controller IC designed for AC/DC power supplies, suitable for applications requiring power factor improvement. It operates in boundary conduction mode (BCM), which helps reduce switching losses and noise through Zero Current Detection (ZCD). This IC features a low total harmonic distortion (THD) circuit and complies with IEC61000-3-2 Class-C standards. Key specifications include an input voltage range of 10 V to 38 V, a typical operating current of 0.58 mA, and an operating temperature range from -40 ¬8C to +105 ¬8C. The device is packaged in an SOP-J8 format, measuring 4.9 mm x 6.0 mm x 1.65 mm. Additional features include a VCC under-voltage lockout (UVLO) function, static over-voltage protection (OVP), and soft start capabilities. The BD7694FJ-E2 is suitable for various applications, including lighting equipment, AC adapters, televisions, and refrigerators.
