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. |
 |
Key Feature 2 : Direct AC connection simplifies LED drive
|
Developing LED lighting involves a number of considerations, including power supply/housing design and LED layout. The BP5870 integrates an AC/DC converter, PFC circuit, and DC/DC converter, simplifying power supply and thermal designs along with circuit pattern. |
 |
Key Feature 3 : Pseudo-resonance method results in 83% efficiency
|
BP5870 utilizes a low-noise, high efficiency pseudo-resonance switching method that minimizes switching loss across the switching MOSFET for 83% efficiency. |
