• RE: ADP1607 boost DCDC; Max Vin voltage is Vout?

    Hi Moto,

    Thank you for all your questions and your interest in the ADP1607.

    1) ADP1607 does not operate in 100% duty cycle mode but there is no implicit minimum on time.

    2) The Max input voltage for the ADP1607 is Vout, which is characterized on…

  • ADP1607 to supply ADAU1761

    I'd like to use the ADP1607 to supplying the ADAU1761 for a mobile audio
    project (single cell).  For suppling by USB or external supply I inteded a LDO.
    To avoid voltage drop I shoudn't use a diode for connecting Vout of the LDO to …
  • 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: Efficiency of ADP1607 at 32 uA

    Hi Meir,

    The graphs provided are for a part that is Auto mode. Auto means that the part will automatically transition between PFM at light loads and PWM at heavy loads to maintain the highest possible efficiency. At the low currents in your application…

  • 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.

  • ADP1607 PWM MODE EFFICIENCY

    Hi,

    I am looking at the ADP1607 datasheet and I can't find an efficiency curve for the ADP1607ACPZN001-R7  which is the permanent PWM mode IC (not auto mode PFM,PWM).

    Basically I have a problem with the 2% deviation in PFN mode and I would like to…

  • ADP1607 Vout not meeting datasheet

    We got our first samples back that has our device with the ADI regulator (ADP1607ACPZN-R7) on there. We are seeing something that I don't understand and may make this regulator unusable.

    We are trying to get an output voltage of 1.875V with a max…

  • 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…
