ROHM Semiconductor BD7693FJ Power Factor Correction Controller
ROHM Semiconductor BD7693FJ Power Factor Correction Controller is a Boundary Conduction Mode (BCM) PFC Controller that provides a simple, high-performance, active Power Factor Correction using minimal external components. The BD7693FJ employs a Zero Current Detection (ZCD) circuit to greatly reduce switching loss and noise. The device also incorporates a circuit lowering Total Harmonic Distortion (THD). The BD7693FJ supports the IEC 61000-3-2 Class C Harmonics Standard, making it ideal for lighting applications.
The ROHM Semiconductor BD7693FJ Power Factor Correction Controller is offered in a 4.9mm x 6.0mm SOP-J8 package with a -40°C to +105°C operating temperature range.
