BP5870 isolated high power LED driver module
Overview
ROHM now offers a high efficiency, high power factor isolated high power LED driver module. The BP5870 includes a PFC circuit and utilizes a pseudo-resonance method for direct AC connection for LED drive, facilitating LED lighting solutions. In addition, the unit meets market needs with a universal input and LED open/short protection circuit. |
Key Feature 1 : PFC circuit built in for a power factor of 0.99
Power factor is heavily influenced by the resistance loss through the power supply and transformer lines. The BP5870 features an active filter method with integrated PFC circuit, resulting in a power factor of 0.99. This ensures compatibility with harmonics as well as compliance with IEC61000-3-2. |
