Top efficiency LED drive developed by ram

By increasing the withstand voltage level of the built-in MOSFET to 80V, the maximum LED current is increased to 250mA/ch, so that the product can be applied to a variety of panel sizes, which is very helpful to reduce the design burden.

Japan's leading semiconductor manufacturer Rom developed a very liquid crystal panel (TV, monitor) to achieve lower power consumption of 4 channel backlight LED driver BD9428". New products using Rom proud of the original control circuit technology, while achieving high efficiency and low noise.

By increasing the withstand voltage level of the built-in MOSFET to 80V, the maximum LED current is increased to 250mA/ch, so that the product can be applied to a variety of panel sizes, which is very helpful to reduce the design burden.

The production process of the product is based on ROHMHamamatsuCo., Ltd. (Hamamatsu, Japan), the latter process production base for ROHMElectronicsPhilippines, Inc. (Philippines), plans to start selling samples from 2013 to September (sample price: 200 yen), from 2013 November began to produce 200 thousand temporary scale production.

LCD panel consumption of electricity, the backlight part of about 7, therefore, its efficiency has been a major issue.

In recent years, the rapid spread of LED, in this context, the Roma optimized power supply voltage LED driver supply LED, made to cut power consumption throughout the LED backlight system for the purpose of the patent, began the development of the industry's leading early models.
