Rom in the LED lighting driver module additional dimming work

Rohm developed new product "LED lighting driver module using AC power driven BP5845W", and in March 2008 4 to 7 days in the Tokyo International Exhibition Center held the "Ming decorative street circulation Renaissance" special exhibition "LED Next Stage" on the display. The product can be used to control the output of the external microcontroller PWM signal dimming. The development of AC power supply products produced by the built-in AC-DC converter driver, which belongs to the fixed output current for the features of "BP58 - series". This is the first time the series equipped with dimming function.

At present, the product can support 1K ~ 20kHz PWM signal. The input voltage is converted from AC to 80 ~ 120V. The output voltage is 12.5 ~ 36V, can output the rated current of 250 ~ 360mA. Up to 9 1W white LED. Light multiple LED, can not be adjusted for each LED light, only unified dimming. At present, the sample has been supplied, the sample price is 2000 yen. Will be produced in May 2008. Plan to put into production, so that can support 300 ~ 20kHz PWM signal
