思旺推出應用在MP3上的1.5v參考電壓源 2006年5月30日,思旺今天推出SE5170,一款專門為MP3設計的精密參考電壓源. SE5170在1.6V到5V的輸入電壓范圍內一直保持很好的線性調整度, 適合MP3這種需要精確的電壓參考的應用. SE5170是為在低電流和低電壓條件下工作設計的精確參考電壓源. SE5170可以從低至1.6V的電源電壓開始工作,并消耗低至8mA的電流.溫度穩定性平均在50ppm/℃. 它適合應用在如MP3、MPEG4這種要求與環境溫度無關的恒定參考電壓的應用中. 此外,SE5170旨在不存在Cin和Cout的條件下穩定工作. 然而,建議把Cin和Cout包括進系統設計中,因為這將提高PSRR.SE5170采用SOT23-3的小封裝形式。SE5170的主要特點： ●最低輸入電壓1.6V ●對地電流8mA（典型值） ●在整個工作溫度范圍內保證5mA的輸出電流. ●極低的溫度漂移50ppm/℃. ●無需Cin和Cout穩定工作. ●標準SOT-23-3L封裝包裝、定價和供應 思旺的SE5170采用3腳SOT23封裝形式，以1,000片為單位批量購買，每片起價為1.0元人民幣.關于思旺電子公司 思旺電子，是一個年輕而充滿活力的專門從事純模擬電路和數模混合集成電路設計的高新技術企業，設計電源管理器件的各種應用. 思旺的尖端產品應用于無線局域網和手機、數碼相機、手機、充電器、電腦、、MPEG4、MP3、便攜DVD、閃存器件. 思旺的產品在美國硅谷和中國北京設計. 在臺北(臺灣)、北京(中國)、深圳(中國)、上海(中國)、舊金山(美國)設有銷售辦公室

思旺用于便攜式應用的雙通道LDO 2006年5月30日,思旺今天推出SE5221、雙通道應用在空間有限并且期望低成本方案的便攜式產品中. 包括手機、MPEG4、藍牙耳機、數碼相機和WLAN. 許多便攜式應用需要兩個不同的電壓,一個用于核心供電,一般在1.5v或1.8v,另一個用于外圍接口,通常在2.8V或3.3V. 大部分PCB版圖中,這兩個電壓彼此非常接近. SE5221為這些應用提供了理想的方案. SE5221是雙通道LDO，可為每通道提供200mA的電流. SE5221設計有特殊的內部帶隙參考,可以提供高于60dB的PSRR,所以不需要外部旁路. 在大多數便攜式應用中，使對地電流最小化以便盡可能的延長電池壽命. 在兩個LDO同時打開時，SE5221在輕負載狀態下典型地消耗36mA.每個通道可單獨關閉,以進一步延長電池壽命. 其他特征包括過電流保護,過溫度保護.SE5221采用SOT23-6的小封裝形式。 SE5221的主要特點: ●典型壓差330mV@200mA ●輸出電流達200mA(每個通道) ●對地電流36mA(典型值) ●雙關斷腳控制每個輸出 ●限流和熱保護 ●SOT-23-6L封裝兩個LDO 包裝、定價和供應 思旺的SE5221采用6腳SOT23封裝形式，以1,000片為單位批量購買，每片起價為2.0元人民幣. 關于思旺電子公司 思旺電子，是一個年輕而充滿活力的專門從事純模擬電路和數模混合集成電路設計的高新技術企業，設計電源管理器件的各種應用. 思旺的尖端產品應用于無線局域網和手機、數碼相機、手機、充電器、電腦、、MPEG4、MP3、便攜DVD、閃存器件. 思旺的產品在美國硅谷和中國北京設計. 在臺北(臺灣)、北京(中國)、深圳(中國)、上海(中國)、舊金山(美國)設有銷售辦公室

思旺推出用于數碼相機和手機的串聯LED驅動 2006年5月21日,思旺今天推出SE3506、高效的白光LED驅動，用于手機、數碼相機、便攜式DVD、MPEG4和其它類似應用的背光. SE3506是一款特別為恒流驅動白光LED設計的升壓DC/DC轉換器. 該器件可以用一節鋰電池驅動二個、三個、四個、五個和六個串聯的LED. 采用LED串聯連接的方法可以提供相同的電流，從而獲得均勻的亮度并無需鎮流電阻器.SE3506的開關頻率為1MHz，因而允許采用小巧的外部組件。由于可使用數值僅為1µF 的輸出電容器，因此，與其它的解決方案相比，在占用空間和成本上均有所節省。95mV 的低反饋電壓最大限度地降低了電流調節電阻器的功耗，從而提高了效率。EN腳可被用來控制SE3506或開關LED。 此外,EN腳可以用來控制LED的亮度,無需改變PCB上的任何元件. 不同占空比的頻率可以發給EN腳，以便控制LED持續工作的時間. LED開通的時間越長越明亮，關斷的時間越長越暗淡. SE3506的輸入電壓可取從低至2.0V到高達5.0V. 這涵蓋了各類鋰電池的整個壽命, 鋰電池一般剛充完電時是4.2V,并在其關斷以前降至約2.7V. SE3506典型地具有僅100mA的電源電流. 這比典型的同類LED驅動小10倍到20倍.這為用電池供電且其中低功耗占重要位置的便攜式應用提供了最大化的能量節約. SE3506有內置的過熱保護(OTP). 當溫度達150℃時,集成電路將進入關閉模式,提供適當的保護. 這保證了SE3506和使用SE3506的產品不會受損. 此外,SE3506內置過電流保護(OCP). 以防意外短路或負載過重. 在某些情況下,如意外短路,過電流和過熱保護將一起工作, 為集成電路和產品提供最佳的保護. SE9016可與SE3506 (白光LED驅動)和SE5221 (雙通道LDO) 配合在手機上應用. 他們為同時配備有鋰電池和液晶顯示器的便攜式應用提供一個通用的芯片組解決方案。.SE3506采用SOT-23-5L的小封裝形式SE3506的主要特點: ●電壓范圍:2.0V-5.0V.●固有匹配的LED電流. ●高效率:85%（典型值）. ●可由一個3.0V電源驅動多達四個LED. ●可由一個3.6V電源驅動多達六個LED. ●快速1MHz開關頻率. ●最大輸出電壓達到35V. ●采用高度僅1mm的纖巧型感應器. ●只需1mF的輸出電容. ●扁平SOT-23-5L封裝. ●電源電流是100mA（典型值）. ●輸出過流保護. ●熱保護. ●2kV以上的ESD保護.●SOT23-5L封裝形式 包裝、定價和供應 思旺的SE3506采用5腳SOT23封裝形式. 關于思旺電子公司 思旺電子，是一個年輕而充滿活力的專門從事純模擬電路和數?；旌霞呻娐吩O計的高新技術企業，設計電源管理器件的各種應用. 思旺的尖端產品應用于無線局域網和手機、數碼相機、手機、充電器、電腦、、MPEG4、MP3、便攜DVD、閃存器件. 思旺的產品在美國硅谷和中國北京設計. 在臺北(臺灣)、北京(中國)、深圳(中國)、上海(中國)、舊金山(美國)設有銷售辦公室
