1緊湊的投影機中的使用
V•I芯片為高性能投影儀終身動力總成
現代的投影技術更通用的比舊的幻燈片顯示投影儀,使圖像、視頻、甚至數據與高清晰度、亮度,甚至可移植性。液晶顯示器投影技術,例如,對比的比例為1。3000該技術使用三種LCD面板作為稜鏡
創建完整的顏色。
這個趨勢預測市場走向移動的減小而增大,更強大的投射者。一個Vicor杠桿的小包裝大小客戶、效率高
我們的V•芯片組件,我在他們的權力結構緊湊、先進發光投影儀專為應用程序,如高分辨率和運動仿真。
在客戶的設計、離散PFC交直流前端提供一個命名384 Vdc兩個384 Vin - 48 Vout并行總線轉換器×10 ^ 8立方公尺。48個V公共汽車使客戶降低線損,使用PRM調節器和VTM電流乘數組合在200 W每設立了三個不同的電壓軌為紅色,綠色和藍色led。我的V•芯片組件提供負載調節為Vout緊密,非常快速瞬態脈沖負載。
2，LCD顯示其中的使用
光明的液晶顯示轉爐×10 ^ 8立方公尺
位移的陰極射線管(CRT)由液晶顯示屏(LCD)技術是完整的。在液晶顯示器、led(發光二極管)已經取代了冷陰極螢光燈(CCFL)提供均勻的白色背光。led相比有顯著的好處CCFLs、規模、效益、純度和可靠性。他們還提供減少有害物質用于制造它們。
LED背光的調控光源從像素像素,創造更實際的圖像與較少的運動模糊。這正是一個Vicor顧客的需要。利用V•我芯片解決方案,他們可以利用一種新的led背光液晶顯示屏。
他們的設計是基于創新的專利技術為高動態范圍(HDR)圖像技術。這項技術使得前途光明的顯示器,即十倍比傳統的液晶顯示器。在每一個單獨的LED背光是如此光可尋址的動態層次,可以改變到微區和空間由微區。結果顯示圖片生動,更亮的光和顏色光譜比先前的可能。
在這以前,led燈是由一個5.5伏直流電,500供電,但那是很高的電流分布有效。里面根據他們的新建筑的客戶在V•我芯片×10 ^ 8立方公尺轉換器。他們的×10 ^ 8立方公尺48 V分布在以更低的電流,提供更有效的權力分配。這個×10 ^ 8立方公尺的直接驅動步進驅動芯片由個人領導下的電壓大電流4V需要的驅動程序。這個×10 ^ 8立方公尺的高度轉換效率和安全操作溫度范圍內允許顧客完成設計沒有散熱器。

-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.
