• RE: ADP5051芯片工作不正常

    当我把ADP5051的输入电压从12V降到6V或者5V的时候,ADP5051工作一切正常,这是什么原因?ADP5051的输入电压范围不是最高15V吗?

  • RE: BUCK and LDO which are not used in ADP5052 are safely set to disable.

    I recommend using the ADP505x design tool.

    This tool has the ability to disable channels and will suggest an appropriate configuration for the un-used pins.

    Here is the link to the ADP505x design tool.

    Dear Sir/Madam,

    Can you send your schematic for ADP5053 EVAL Board?

    The following your schematic was bad picture so I cannot pick up the value and part # all.

  • RE: ADP505X OVP delay time

    Hello!

     

    Good day. Please be noted that the latch-off protection for short-circuit and overvoltage conditions is optional and is enabled:

    • via I2C (for ADP5050 and ADP5051) or
    • by factory fuse (for ADP5050, ADP5051, ADP5052 and ADP5053).

  • ADP 5051 SWITCHING FREQUENCY SELECTION IN DESIGN TOOL

    Dear Sir/Madam,

    I'm using ADP 5051 quad buck regulator for FPGA  power inputs. We have to select switching frequency @ 1MHZ for that in design tool there is no specific option.Input voltage is 14V, and out put reqirements are 1.2V/4A,3.3V/4A,1.8V…

  • ADP5051第三通道的SW的开关很信号不正常,且有5V的直流偏置!

    你好,我电路板上ADP5051输出四路电源,一二,四通道分别输出1.2V,2.5V,3.3V,且都正常,电路和datasheet上的参考图一样,图如下:;但第三通道输出5V,不正常,测得SW上的波形如下:

    放大了如下:

    而且,SW上面有5V的直流,这是不是芯片的三通道坏了,但其他的三鹿通道都是正常的。麻烦,你们给我分析下故障,十分着急,谢谢!

  • ADP5051可调输出电压问题

    你好,ADI工程师,我公司现在在用ADP5051的芯片,

    调试过程如下:

    测试条件:  ADP输入12V,RT=31.6K,(600KHZ);ADP5051 SYNC/MODE上拉5V,启动FPWM模式;

    设计输出:  通道1输出1.2V/4A;通道2输出2.5V/4A,通道3,4输出3.3V/1.2A;

    通道1,2电路原理图如下:

    存在问题:

    1.每次上电,芯片四个通道的SW引脚有时候有输出;

    2.通道3,4能正常工作,输出3.3V电压;但通道1,2不能输出1.2V 和 2.5V电压…
