Any and all SANYO products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability,such as life-support systems,aircraft’s control systems,or other applications whose failure can be reasonably expected to result in serious physical and/or material damage. Consult with your SANYO representative nearest you before using any SANYO products described or contained herein in such applications.SANYO assumes no responsibility for equipment failures that result from using products at values that exceed,even momentarily, rated values (such as maximum ratings,operating condition ranges,or other parameters) listed in products specifications of any and all SANYO products described or contained herein.Monolithic Linear ICVertical Deflection Output Circuitwith Driver for Color TV UseOrdering number:ENN2863LA7835SANYO Electric Co.,Ltd. Semiconductor CompanyTOKYO OFFICE T okyo Bldg., 1-10, 1 Chome, Ueno, T aito-ku, TOKYO, 110-8534 JAPANPackage Dimensionsunit:mm3107-SIP13H[LA7835]SANYO : SIP13HOverviewThe LA7835 is an IC that contains the vertical deflection output circuit with a driver for small-aperture (maximum deflection current 1.8Ap-p) color/B&W TV, monitor/dis-play use and is placed in a SIP13H package. The LA7835has such features as greatly reduced number of external parts and low power dissipation. Since both DC feedback and AC feedback can be provided inside the IC, it is easy to design the vertical deflection circuit. The LA7835 can be used in conjunction with single-chip IC LA7650 (NTSC),LA7680 series (PAL/NTSC) (VIF, SIF, video, chroma, and deflection circuit) to provide all the functions required for color TV signal processing.Features•Low power dissipation because of on-chip pump-up cir-cuit.• On-chip 50/60Hz vertical size control circuit.• On-chip ramp generator.• On-chip driver circuit.• Vertical output circuit.• On-chip thermal protection circuit.• Minimum number of parts required.SpecificationsMaximum Ratings at Ta = 25˚C˚C ˚C re t e m a r a P lo b m y S s n o i t i d n o C sg n i t a R t i n U e g a t l o v y l p p u s r e w o p r e v i r D V +1C C x a m 51V e g a t l o v y l p p u s r e w o p p u -p m u P V +7C C xa m 03V e g a t l o v y l p p u s r e w o p t u p t u O V +21C C xa m 26V t n e r r u c t u p t u o n o i t c e l f e D I F E D 5.1+o t 5.1–o -p A n o i t a p i s s i d r e w o p e l b a w o l l A x a m d P kn i s t a e h e t i n i f n i h t i W 8We r u t a r e p m e t g n i t a r e p O r p o T 58+o t 02–e r u t a r e p m e t e g a r o t S g t s T 051+o t 04–ec n a t s i s e r l a m r e h T θc-j 4˚C/W0.40.53.41.1525.610.02.42.01.22.00.81131.0m i n4.515.4m a x11.811.2 13.9 查询LA7835供应商捷多邦,专业PCB打样工厂,24小时加急出货Operating Characteristics at Ta = 25˚C, +VCC1=12V, +V CC7=24VOperating Supply Voltage ConditionsRecommended Operating Conditionsre t e m a r a P l o b m y S sn o i t i d n o C sg n i t a R t i n U e g a t l o v y l p p u s r e v i r D V +1C C 41o t 8V eg a t l o v y l p p u s p u -p m u P V +7C C 72o t 01Vre t e m a r a P l o b m y S sn o i t i d n o C sg n i t a R t i n U e g a t l o v y l p p u s r e v i r D V +1C C 21)9(V e g a t l o v y l p p u s p u -p m u P V +7C C 42V tn e r r u c t u p t u o n o i t c e l f e D I p-p 118.1o t p u p-p A re t e m a r a P l o b m y S sn o i t i d n o C sg n i t a R t i n U n i m p y t x a m t n e r r u c t n e c s e i u q y l p p u s r e w o p r e v i r D I 1C C 8.18.28.3A m e g a t l o v d l o h s e r h t t u p n i r e g g i r T V 28.21.34.3V e g a t l o v n i p l o r t n o c e z i s l a c i t r e V V 39.51.63.6V e g a t l o v t r a t s e p a h s m r o f e v a w p m a R V P M A R 7.40.53.5V e g a t l o v n o i t a r u t a s e g r a h c p u -p m u P V 01-8S 5.1V e g a t l o v n o i t a r u t a s e g r a h c s i d p u -p m u P V 8-7S A 9.0=I 0.3V )r e w o l (e g a t l o v n o i t a r u t a s t u p t u o n o i t c e l f e D V 01-11S A 9.0=I 2.1V )r e p p u (e g a t l o v n o i t a r u t a s t u p t u o n o i t c e l f e D V 11-21S A9.0=I 2.3V t n e r r u c g n i l d I 612223A m ni a g e g a t l o V G V OzH k 1=f 95Bd Pin Assignment and Block DiagramEquivalent CircuitSample Application CircuitNote) The values in parentheses are for a sample application where the V CC1 is 9V.Proper Cares in Using the LA7835Note1)If horizontal components are mixed into pin 1, causing the interlace characteristic to worsen, provide decoupling as shown above. The resistor value and capacitor value are shown as an example.2)If oscillation occurs, connect the OSC blocking circuit as shown above.However, if the deflection current increases, oscillation may not be blocked completely. In this case, change the application circuit as shown below.3)In some applications, the OSC blocking capacitor across pins 9 and 11 is connected across pin 9 and GND.4)The threshold voltage on pin 2 is +V CC11/4. Set the input trigger level so that it intersects this threshold level.The LA7835 operates on the negative transition of the trigger pulse.5)Connect the radiator fin to GND.。
三洋49dolby电视说明书关于使用:1、机器自带低功耗分列试设计音箱,在TV模式下,无需要任何设备和连线便能听到声音!在PC模式下,只需要买一条音频线连接到电脑主机,便可以实现音箱的功能(关于接电视设置:接上闭路线后,在TV模式下,进入电视主菜单找到彩色设置-—PAL DK模式,然后再选择“自动搜台”后即可)2、可以连接电脑主机,标准的16:9比例,标准的1366*768高清分辨率,根据电脑主机显卡决定!正确使用刷新频率为60HZ(更新显卡驱动后一定要重新启动电脑)3、能够连接普通有线和高清数字电视机顶盒收看电视节目(天锅卫星都可以的)输入接口为AV三色接口(黄色、白色、红色)、TV 接口。
4、可以连接DVD,输入接口可以使用S端子或者AV(推荐使用正版光盘)注意事项:一、日常使用,避免连续、长时间工作,尽量避免长时间显示同一张画面。
和显像管电视一样,液晶显示屏也会因为长时间工作引起内部的老化或被烧坏,尤其糟糕的是长时间内显示同一画面。
如果长时间地连续显示一个国定的内容,就有可能导致某些LCD像素过热,进而造成内部产生坏点。
而这种损坏是不可逆的,且不能修复。
因此在使用时应该注意:不用的时候,关闭显示屏如果只是暂时不用,就选择屏幕保护程序,或者把显示屏的亮度调低一点。
不过这些保护程序只是保护液晶屏,后面的灯管还一直在工作,所以直接关闭显示屏更稳妥。
二、放置的地方,环境要保持干燥并远离化学药品。
如果电视放置的环境湿度很大,电器内部就会结露,容易造成漏电、短路等。
如果不小心湿气进入液晶显示屏,就必须将电视换置到较温暖的地方,以便让其中的水分挥发掉。
平时家庭中使用的发胶、灭蚊剂等都是挥发性很高的化学品,也会对液晶显示屏造成损伤,要尽量远离液晶电视。
三、液晶显示屏不能频繁清洗。
液晶电视使用久了,屏幕就会成为“大花脸”,怎么办?正确的清理方法:拿一块沾有少许玻璃清洁剂的特殊屏幕擦布,小心地把污迹擦去,擦拭时力度要轻,否则显示屏会因此而短路损坏。
