• LTC3556 Formula clarification


    Hi,

    I am  considering to use the LTC3556 in a new design and have a question about the formula used to program the output voltage of the regulators.
    The formula from the datasheet is shown as follows:


    However, the output voltage derived from the resistor…

  • LTC3556: Disable buck converters

    Hi, 

    We are using the LTC3556 in our new design and would like to know if it is possible to disable any of the buck converters without using the I²C configuration. It is possible that one of the converters will not be used in the system, and we would…

  • Revision of LTC3556 Schematic / Layout

    Hi,

    I would like to request a schematic and layout review of the LTC3556 circuit we are using in our design.

    Please refer to the attached files. 

    Thanks!

    Best Regards,

  • Recommended Layout for LTC3556 or DC1296 gerber files

    Is there a recommended layout for LTC3556 device?

    If not, is it possible to get the gerber files for the DC1296?

  • LTC3556: can it handle the following 3.3/3.3/5V configuration?

    Good day!

    1. Can LTC3556 handle 3.3V/400mA + 3.3V/400ma + 5V/200mA configuration?
    The datasheet clearly states Vout for Buck-Boost regulator (5.5V max), but it is not completely clear about  max Vout for 2 buck regulators.
    Max P is ~5W (with battery charging…

  • For LTC3556, if we tie LDO3v3 to VOUT (as per the datasheet), do we still need to place the 1uF capacitor on the LDO3V3 pin?

    If we tie LDO3v3 to VOUT on LT3556 as per the datasheet on page, do we still need to place the 1uF capacitor on pin 1? We already have 10uF on the Vout net as per datasheet.

  • RE: LTC4065L connection to active circuit

    The LTC3554 is a good choice since it is actually designed for the 50-100mA range of charging current.  You will have the option of using the on-board buck converters if you wish. 

    You may also consider the LTC3556 if you don't mind including switchmode…

  • Can we operate the two Buck converters on the LT3556 device in parallel

    Hello, 

    We are attempting to design in the LTC3556 into a client's consumer electronics device. However, we are unable to simulate since it is not supported. Do you happen to know if we can use the two buck converters in parallel to drive a 600mA load…

  • RE: LIPO Power Management

    The only way I know of to reduce the trickle charge is to change the Prog resistor. That will also change the full charge current.

    I know there are other parts out there that have different trickle charge currents and longer/programable timers. I do not…
