• RE: 求推荐电源芯片：1.8v或2.5v升压到3.3V的电源芯片

    ADP1607,LTC3536都可以

  • RE: How to set the resistors to make ADP 5090 runs from 2.2V to 2.5V without battery.

    maybe you can try ADP5091 that includes additional regulated output even if the battery higher than 2.5V.

    another one is boost regulator ADP1607.

  • ADP PFM mode

    ADP1607

    In the datasheet is said:

    In PFM mode, the converter only switches when necessary to keep the output voltage between the PFM comparator high output voltage threshold and the lower sleep mode exit voltage threshold. Switching stops when the upper…

  • RE: i wants to make an DC voltage amplifier

    Atul,

    As Bob suggested this is some related to power management.

    The ADP1607 boost regulator can generate a bias voltage (2.5V) for another boost regulator like the ADP1612.

    In this case the the ADP1612/13 can boost to 3.3V or 5V from the battery by…

  • 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…

  • RE: ADAU1461 Hardware Circuit

         Hello,

         I'm afraid I don't have your complete solution.  Here's a few ideas:

    • DC-DC Converter:     To power your system, try the ADP1607 boost IC.  The application circuit from its datasheet can convert inputs from 0.8V to 3.3V up to 3.3V.

  • RE: adau1772 MCU interface

    Hello okokok,

    Have a look at the evaluation board schematic and user guide. In the user guide there is a short discussion about using the I2S ports. It is a pretty standard way to use I2S. You have to use I2S since there is no way to get audio in and…
