BP5873 isolated high power LED driver module
Overview
ROHM's isolated high power LED driver module (BP5873) meets the needs of LED lighting equipment by integrating all required functions into one package. |
Key Feature 1 : Single converter system improves efficiency
The single converter system integrates an AC/DC converter with PFC circuit, reducing loss considerably compared with dual-converter methods, improving efficiency up to 85%. |
|
Key Feature 2 : PFC circuit built in for a power factor of 0.99
The power factor is greatly affected by resistance loss through the tranformer windings and supply lines. BP5873 features an active filter method with built-in PFC circuit, resulting in a power factor of 0.99. This not only enables high frequency operation, but ensures compliance with the IEC61000-3-2 standard. |
|
Key Feature 3 : Thinner form factor approaching that of the LED units themselves
One major advantage of LEDs compared with conventional lighting is that they have a thinner form factor. The BP5873 can drive a wide range of LED lighting devices and features a thickness of only 15mm - roughly 30% thinner than competitor models. |
|
Key Feature 4 : Change the color temperature via analog input
There is an increasing demand for changing the color temperature of the LED lighting device to suit the desired mood, similar to dimming. The BP5873 provides two outputs for connecting LEDs with different color temperatures, making it possible to change the lighting environment dramatically. |
