V•I芯片BCM,,PRM及VTM在固态照明/显示器中的使用
1紧凑的投影机中的使用
V•I芯片为高性能投影仪终身动力总成
现代的投影技术更通用的比旧的幻灯片显示投影仪,使图像、视频、甚至数据与高清晰度、亮度,甚至可移植性。液晶显示器投影技术,例如,对比的比例为1。3000该技术使用三种LCD面板作为稜镜
创建完整的颜色。
这个趋势预测市场走向移动的减小而增大,更强大的投射者。一个Vicor杠杆的小包装大小客户、效率高
我们的V•芯片组件,我在他们的权力结构紧凑、先进发光投影仪专为应用程序,如高分辨率和运动仿真。
在客户的设计、离散PFC交直流前端提供一个命名384 Vdc两个384 Vin - 48 Vout并行总线转换器×10 ^ 8立方公尺。48个V公共汽车使客户降低线损,使用PRM调节器和VTM电流乘数组合在200 W每设立了三个不同的电压轨为红色,绿色和蓝色led。我的V•芯片组件提供负载调节为Vout紧密,非常快速瞬态脉冲负载。
2，LCD显示其中的使用
光明的液晶显示转炉×10 ^ 8立方公尺
位移的阴极射线管(CRT)由液晶显示屏(LCD)技术是完整的。在液晶显示器、led(发光二极管)已经取代了冷阴极萤光灯(CCFL)提供均匀的白色背光。led相比有显著的好处CCFLs、规模、效益、纯度和可靠性。他们还提供减少有害物质用于制造它们。
LED背光的调控光源从像素像素,创造更实际的图像与较少的运动模糊。这正是一个Vicor顾客的需要。利用V•我芯片解决方案,他们可以利用一种新的led背光液晶显示屏。
他们的设计是基于创新的专利技术为高动态范围(HDR)图像技术。这项技术使得前途光明的显示器,即十倍比传统的液晶显示器。在每一个单独的LED背光是如此光可寻址的动态层次,可以改变到微区和空间由微区。结果显示图片生动,更亮的光和颜色光谱比先前的可能。
在这以前,led灯是由一个5.5伏直流电,500供电,但那是很高的电流分布有效。里面根据他们的新建筑的客户在V•我芯片×10 ^ 8立方公尺转换器。他们的×10 ^ 8立方公尺48 V分布在以更低的电流,提供更有效的权力分配。这个×10 ^ 8立方公尺的直接驱动步进驱动芯片由个人领导下的电压大电流4V需要的驱动程序。这个×10 ^ 8立方公尺的高度转换效率和安全操作温度范围内允许顾客完成设计没有散热器。

-Description
The V•I Chip Bus Converter Module (BCM) is a Sine Amplitude Converter that offers superior performance, the highest efficiency, and highest power density in the smallest package available. BCMs provide an isolated intermediate bus voltage to power non-isolated POL (Point-of-Load) converters or serve as an isolated voltage source for ATE, server, telecom, and industrial control applications. Some additional features include:
· Fast response time
· Low noise
· Saves board area, materials and total system cost
· Through-hole option available, except in half-chip package
Full-chip and half-chip BCMs are compatible with standard pick-and-place and surface-mount assembly processes.

-Description
The PRM is a very efficient non-isolated regulator capable of both boosting and bucking a wide range input voltage and provides a regulated, adjustable output voltage or "Factorized Bus". PRMs can be used stand-alone as non-isolated voltage regulators or combined with VTMs for a complete isolated, DC-DC solution with higher efficiency and power density. The VTM provides point-of-load, fixed ratio voltage transformation with extremely fast transient response and isolation to 2,250 Vdc. Additional features include:
· Small footprint
· Low weight
· Bulk capacitance elimination
· Through hole option available, except in half-chip package
