• LDO Voltage Regulator ADP162: use a pull-down external resistor

    Hi, I am using the LDO Voltage Regulator ADP162 but I do not find in the datasheet if it is necessary to use a pull-down external resistor in the enable pin. In principle, this enable pin will be controlled by a GPIO pin of the MSP430G2553 MCU. Thank…

  • RE: Startup issue ADP5090

    Hi Michael,

    That should be safe. in factor, you can calculate the rough voltage drop during transist the energy from SYS and BAT to ADP162 output capacitor considering to the peak current of the ADP162 startup.

    Regards,

  • RE: boost + LDO

    Hello,

    This looks like a very good application for the ADP162.  I would also include a ferrite bead pi filter before the LDO to try and eliminate some of the high frequency switching noise from the boost converter.  I assume you are using the ADP1607 as…

  • ADP160-IGND Max

    In the ADP160/ADP161/ADP162/ADP163 datasheet, table 1 states IGND maximum @
    Iout=10mA is 19uA, but in the figure 16 IGND @ Iout=10mA can be 100uA (when Vin
    is 3.3v).


    Can you clarify?

     

    The parameters in Table 1 are only valid for…
  • ADM1266 Leakage Current

    Hello,

    I've taken over support for a CPU board developed by another engineer at Arista.  In this design, there's a 3.3V CR2032 coin cell which is converted to 1.5V by an ADP162 LDO.  This rail feeds the RTC of the x86 and is monitored by VP11 of…

  • ADI可穿戴设备电源管理解决方案

    可穿戴设备正集成越来越多的功能,这为电源管理带来挑战。可穿戴设备中的电池通常非常小,设备又需要长时间工作而不用充电,因此功耗是一个关键的设计考虑因素。对于可穿戴设计电源管理,ADI会提出怎样的一个解决方案呢?看看ADI亚太区医疗行业市场经理王胜怎么说吧!

     

    迎合电源管理低功耗、小体积及低成本要求

    “可穿戴设备本身是很宽泛的概念覆盖各类产品形态,包括传统便携设备(如手表),也包括在非设备类的穿戴产品中附件上各类传感器进而成为可穿戴设备的范畴,例如衣服鞋帽等。可穿戴设备所提供的功能目前多集中在在工具类…
