ROHM has released an updated version of the instant auto dimming LED driver product BD6095GU

Topic: ROHM Co., Ltd., a semiconductor manufacturer headquartered in Kyoto, Japan, has released an updated version of the instant auto-dimming LED driver product BD6095GU, which can correspond to the LED backlight module of the LCD panel, and will effectively improve the use of white LEDs in backlight modules. Luminous properties. ROHM pointed out that the sample of this product can be shipped in October 2007, the sample price is 500 yen, scheduled to start in February 2008, mass production of 500,000 pieces per month, the front part of this LED driver product The process was carried out at ROHM's Hamamatsu company in Shizuoka Prefecture, Japan, and the latter process was carried out at ROHM Fukuoka, Fukuoka Prefecture, Japan.



The company said that with the rapid development of various portable devices such as game consoles, mobile phones, and digital navigation systems, it is important to maintain image signals for a long time display, and the LCD module will have fatigue for a long time of gaze. The need for automatic dimming, and LED module for power saving, and BD6095GUL this LED backlight driver, coupled with a brightness sensor, can produce up to 256-segment adjustment. The dimming function of the new product is estimated to enable the white LED backlight module using this IC to save one-third of the power consumption of the previous product.

The main features of BD6095GUL:

1. Built-in automatic dimming function, with the brightness sensor connected to the LCD backlight module, can automatically adjust for the surrounding brightness and darkness.
2, can work with the external PWM mechanism, in the case of film display, can also adjust the backlight brightness.
3, built-in high efficiency x1.33 boost circuit.
4, can be used with brightness sensing ICBH1600FVC.
5. When the PWM is operated, the fluctuation of the booster circuit can be minimized to prevent the external condenser from generating sound.
6. When the automatic dimming is performed, the backlight current is adjusted to a stage of 8 bits, and the adjustment of 256 steps can be performed based on 0.1 milliamperes (mA).

Fan Heater

Heater is a combination of fans, motors and air heaters combined unit. Applicable to all types of workshops, when the air is free of dust and flammable or explosive gas, can be used as a circulating air heating. Heater can be used independently as a heating, generally used to supplement the lack of heat sink parts or the use of radiators as the duty of heating, the remaining heat load borne by the heater.

(1) horizontal blower: indoor air from the side of the inhalation, the heat exchanger after the heat, the horizontal direction. The jet has a certain range, so that the heating zone is fully blended, the temperature is evenly mixed.

(2) top blower fan: axial fan placed in the bottom of the unit, the air from the side of the heater into the air through the standing heat exchanger, and then sent down. In order to make the jet face to be discharged downward, a guide vane for diffusion is provided at the outlet of the fan.

(3) floor heaters: such units of the large amount of air, send hot air range far, can afford a larger area of heating. When running, the noise is large. Applicable to the factory building heating.

The advantage of heater heating is [2]:
(1) single machine heat supply, in the same heat load, the number of end devices used less;
(2) small heaters can be hanging, do not take up the building area, large heaters floor installation, covers an area of limited;
(3) start heating up fast.
