1，GDRV是什么意思 電視機(jī)項(xiàng)目數(shù)據(jù)

2，64位win7頻繁藍(lán)屏看記錄都是gdrvsys引起什么情況 藍(lán)屏的種類有很多種，究其原因也十分復(fù)雜。不過(guò)想徹底解決藍(lán)屏我有小小心得。出現(xiàn)藍(lán)屏的原因往往集中在不兼容的硬件和驅(qū)動(dòng)程序、有問(wèn)題的軟件、病毒等。請(qǐng)按如下方法排除解決：1、硬盤連線是否松動(dòng)；無(wú)異常后，對(duì)硬盤進(jìn)行查錯(cuò)處理；2、系統(tǒng)是否有病毒，建議安全模式下掃描殺毒； 3、把BIOS恢復(fù)出廠狀態(tài)試試；4、裝系統(tǒng)后硬件的驅(qū)動(dòng)程序是否安裝成功？ 5、最好先重裝操作系統(tǒng)； 6、如重裝系統(tǒng)后仍有問(wèn)題，則極可能是硬件不兼容所致； 7、向商家或周圍熟悉電腦的朋友咨詢一下也好，或許他們會(huì)給予幫助； 8、祝你好運(yùn)！ 望能幫到朋友你！

3，TPS40210芯片BP腳的功能是什么接了一個(gè)電容對(duì)地電容壞了電壓就沒(méi)有了 網(wǎng)上很方便查，5 Pin Configuration and FunctionsDGQ10-PinTop ViewDRC10-PinTop ViewPin FunctionsPINI/ODESCRIPTIONNAMENO.BP 9 O Regulator output pin. Connect a 1.0 μF bypass capacitor from this pin to GND. 穩(wěn)壓器輸出引腳。 在此引腳與GND之間連接一個(gè)1.0μF旁路電容。BP就是旁路（ByPass）的意思。一般是自舉電容之類的。由于芯片內(nèi)部制造電容電感很困難（制造半導(dǎo)體器件如晶體管卻很容易），所以設(shè)計(jì)時(shí)把集成電路中需要接電容的地方用引腳引出來(lái)，在芯片外面接。所以越大的芯片引腳越多，四周放的電容也越多。COMP 4 O Error amplifier output. Connect control loop compensation network between COMP pin and FB pin. DIS/EN 3 I Disable pin. Pulling this pin high， places the part into a shutdown mode. Shutdown mode is characterized by a very low quiescent current. While in shutdown mode， the functionality of all blocks is disabled and the BP regulator is shut down. This pin has an internal 1 MΩ pull-down resistor to GND. Leaving this pin unconnected enables the device. FB 5 I Error amplifier inverting input. Connect a voltage divider from the output to this pin to set output voltage. Compensation network is connected between this pin and COMP. GDRV 8 O Connect the gate of the power N channel MOSFET to this pin. GND 6 - Device ground. ISNS 7 I Current sense pin. Connect an external current sensing resistor between this pin and GND. The voltage on this pin is used to provide current feedback in the control loop and detect an overcurrent condition. An overcurrent condition is declared when ISNS pin voltage exceeds the overcurrent threshold voltage， 150 mV typical. RC 1 I Switching frequency setting pin. Connect a resistor from RC pin to VDD of the IC power supply and a capacitor from RC to GND. SS 2 I Soft-start time programming pin. Connect capacitor from SS pin to GND to program converter soft-start time. This pin also functions as a timeout timer when the power supply is in an overcurrent condition. VDD 10 I System input voltage. Connect a local bypass capacitor from this pin to GND. Depending on the amount of required slope compensation， this pin can be connected to the converter output. See Application Informationsection for additional details.
