思旺推出應(yīng)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(shè)計(jì)的精密參考電壓源. SE5170在1.6V到5V的輸入電壓范圍內(nèi)一直保持很好的線性調(diào)整度, 適合MP3這種需要精確的電壓參考的應(yīng)用. SE5170是為在低電流和低電壓條件下工作設(shè)計(jì)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(wěn)定性平均在50ppm/℃. 它適合應(yīng)用在如MP3、MPEG4這種要求與環(huán)境溫度無關(guān)的恒定參考電壓的應(yīng)用中. 此外,SE5170旨在不存在Cin和Cout的條件下穩(wěn)定工作. 然而,建議把Cin和Cout包括進(jìn)系統(tǒng)設(shè)計(jì)中,因?yàn)檫@將提高PSRR.SE5170采用SOT23-3的小封裝形式。SE5170的主要特點(diǎn)： ●最低輸入電壓1.6V ●對地電流8mA（典型值） ●在整個(gè)工作溫度范圍內(nèi)保證5mA的輸出電流. ●極低的溫度漂移50ppm/℃. ●無需Cin和Cout穩(wěn)定工作. ●標(biāo)準(zhǔn)SOT-23-3L封裝包裝、定價(jià)和供應(yīng) 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(jià)為1.0元人民幣.關(guān)于思旺電子公司 思旺電子，是一個(gè)年輕而充滿活力的專門從事純模擬電路和數(shù)模混合集成電路設(shè)計(jì)的高新技術(shù)企業(yè)，設(shè)計(jì)電源管理器件的各種應(yīng)用. 思旺的尖端產(chǎn)品應(yīng)用于無線局域網(wǎng)和手機(jī)、數(shù)碼相機(jī)、手機(jī)、充電器、電腦、、MPEG4、MP3、便攜DVD、閃存器件. 思旺的產(chǎn)品在美國硅谷和中國北京設(shè)計(jì). 在臺北(臺灣)、北京(中國)、深圳(中國)、上海(中國)、舊金山(美國)設(shè)有銷售辦公室

思旺用于便攜式應(yīng)用的雙通道LDO 2006年5月30日,思旺今天推出SE5221、雙通道應(yīng)用在空間有限并且期望低成本方案的便攜式產(chǎn)品中. 包括手機(jī)、MPEG4、藍(lán)牙耳機(jī)、數(shù)碼相機(jī)和WLAN. 許多便攜式應(yīng)用需要兩個(gè)不同的電壓,一個(gè)用于核心供電,一般在1.5v或1.8v,另一個(gè)用于外圍接口,通常在2.8V或3.3V. 大部分PCB版圖中,這兩個(gè)電壓彼此非常接近. SE5221為這些應(yīng)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(shè)計(jì)有特殊的內(nèi)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(shù)便攜式應(yīng)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(gè)LDO同時(shí)打開時(shí)，SE5221在輕負(fù)載狀態(tài)下典型地消耗36mA.每個(gè)通道可單獨(dú)關(guān)閉,以進(jìn)一步延長電池壽命. 其他特征包括過電流保護(hù),過溫度保護(hù).SE5221采用SOT23-6的小封裝形式。 SE5221的主要特點(diǎn): ●典型壓差330mV@200mA ●輸出電流達(dá)200mA(每個(gè)通道) ●對地電流36mA(典型值) ●雙關(guān)斷腳控制每個(gè)輸出 ●限流和熱保護(hù) ●SOT-23-6L封裝兩個(gè)LDO 包裝、定價(jià)和供應(yīng) 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(jià)為2.0元人民幣. 關(guān)于思旺電子公司 思旺電子，是一個(gè)年輕而充滿活力的專門從事純模擬電路和數(shù)模混合集成電路設(shè)計(jì)的高新技術(shù)企業(yè)，設(shè)計(jì)電源管理器件的各種應(yīng)用. 思旺的尖端產(chǎn)品應(yīng)用于無線局域網(wǎng)和手機(jī)、數(shù)碼相機(jī)、手機(jī)、充電器、電腦、、MPEG4、MP3、便攜DVD、閃存器件. 思旺的產(chǎn)品在美國硅谷和中國北京設(shè)計(jì). 在臺北(臺灣)、北京(中國)、深圳(中國)、上海(中國)、舊金山(美國)設(shè)有銷售辦公室

思旺推出用于數(shù)碼相機(jī)和手機(jī)的串聯(lián)LED驅(qū)動 2006年5月21日,思旺今天推出SE3506、高效的白光LED驅(qū)動，用于手機(jī)、數(shù)碼相機(jī)、便攜式DVD、MPEG4和其它類似應(yīng)用的背光. SE3506是一款特別為恒流驅(qū)動白光LED設(shè)計(jì)的升壓DC/DC轉(zhuǎn)換器. 該器件可以用一節(jié)鋰電池驅(qū)動二個(gè)、三個(gè)、四個(gè)、五個(gè)和六個(gè)串聯(lián)的LED. 采用LED串聯(lián)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(zhèn)流電阻器.SE3506的開關(guān)頻率為1MHz，因而允許采用小巧的外部組件。由于可使用數(shù)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(jié)省。95mV 的低反饋電壓最大限度地降低了電流調(diào)節(jié)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(guān)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(fā)給EN腳，以便控制LED持續(xù)工作的時(shí)間. LED開通的時(shí)間越長越明亮，關(guān)斷的時(shí)間越長越暗淡. SE3506的輸入電壓可取從低至2.0V到高達(dá)5.0V. 這涵蓋了各類鋰電池的整個(gè)壽命, 鋰電池一般剛充完電時(shí)是4.2V,并在其關(guān)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(qū)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(yīng)用提供了最大化的能量節(jié)約. SE3506有內(nèi)置的過熱保護(hù)(OTP). 當(dāng)溫度達(dá)150℃時(shí),集成電路將進(jìn)入關(guān)閉模式,提供適當(dāng)?shù)谋Ｗo(hù). 這保證了SE3506和使用SE3506的產(chǎn)品不會受損. 此外,SE3506內(nèi)置過電流保護(hù)(OCP). 以防意外短路或負(fù)載過重. 在某些情況下,如意外短路,過電流和過熱保護(hù)將一起工作, 為集成電路和產(chǎn)品提供最佳的保護(hù). SE9016可與SE3506 (白光LED驅(qū)動)和SE5221 (雙通道LDO) 配合在手機(jī)上應(yīng)用. 他們?yōu)橥瑫r(shí)配備有鋰電池和液晶顯示器的便攜式應(yīng)用提供一個(gè)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(diǎn): ●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(gè)3.0V電源驅(qū)動多達(dá)四個(gè)LED. ●可由一個(gè)3.6V電源驅(qū)動多達(dá)六個(gè)LED. ●快速1MHz開關(guān)頻率. ●最大輸出電壓達(dá)到35V. ●采用高度僅1mm的纖巧型感應(yīng)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(hù). ●熱保護(hù). ●2kV以上的ESD保護(hù).●SOT23-5L封裝形式 包裝、定價(jià)和供應(yīng) 思旺的SE3506采用5腳SOT23封裝形式. 關(guān)于思旺電子公司 思旺電子，是一個(gè)年輕而充滿活力的專門從事純模擬電路和數(shù)模混合集成電路設(shè)計(jì)的高新技術(shù)企業(yè)，設(shè)計(jì)電源管理器件的各種應(yīng)用. 思旺的尖端產(chǎn)品應(yīng)用于無線局域網(wǎng)和手機(jī)、數(shù)碼相機(jī)、手機(jī)、充電器、電腦、、MPEG4、MP3、便攜DVD、閃存器件. 思旺的產(chǎn)品在美國硅谷和中國北京設(shè)計(jì). 在臺北(臺灣)、北京(中國)、深圳(中國)、上海(中國)、舊金山(美國)設(shè)有銷售辦公室
