  • 请问LT8608可以输出负电压使用吗?

    我知道LT8608是Buck架构,只能降压,只能输出正电压,常规使用的话是不能输出负电压的。

    我的意思是将原电路的正输出接地GND,而原GND就作为负电压输出。

    也就是将原Buck架构转换成了Buck-Boost架构,就能输出负电压了。

    所以请问LT8608可以这样做吗?

    2.在LTspice XVII软件仿真是可行的,但是实际做PCB实物测试也可以吗?

    如果不可以,请问为什么不可以?

    如果可以,那是不是说Buck架构的电源芯片都可以这么转换使用从而输出负压?那ADI产品系列还有叫…

  • LT8608 HEATING

    Hi ADI team, 

    we have developed a board with LT8608. i/p is 24V , o/p is 5V/ 1A, we are using hardly 100- 200mA current in max load condition. we found some ic is heating up to 45C+. other remaining IC temp is normal like room temp. what is the cause?…

  • LT8608 or LT8609 with negative output

    Hello,

    I am trying to use the LT8608 as a positive to negative voltage converter as described for example linear technology design note 1021.

    The simulation in LTSpice works fine, producing -6V from 15V supply. Necessary output current is less than 1A…

  • LT8608 Vin idle/quiescent current at no load

    Hi,

    with 24V at Vin and Ven the input supply current is 21mA eq 504mW.

    The datasheet contains no specs about the current with no load.

    This value sounds a bit high to me. Please confirm that this is normal behavior for a LT8608.

  • TSP62840 Replace - nanopower buck recommend request.

    Dear, 

    I am looking for a product that meets the following conditions for nano power buck.

    Replacement part : TSP62840YBGR 

    it is 60nA quiescent current. 

    I checked ADI product. (LTC3388-3 - 720nA, LT8608 - 2.5uA)

    Could you please advice nano power product…

  • LT3045/LT3045-1 - PCB Layout Suggestion For Use In Larger System

    The LT3045/LT3045-1 datasheet and eval board manual show a specific layout for preserving PSRR where the LT3045 is preceded by a switching regulator.  However, the datasheet and eval board manual only cover a standalone regulator and do not show it incorporated…

  • RE: Low IQ LDO's, buck converters

    If your application uses the SHDN/EN/RUN pin (name differs from part to part) to enable/disable the regulator the quiescent current will be below 1uA. This is correct for nearly all regulators (switched mode and/or LDO). We do not specify this more in…
