• LT8228 USV with Supercharger Capacitor

    Hello,

    Question: Why drops the LT8228 in Boost modus the Voltage down when the voltage at the capacitor falls below 6.5 V?

    Above 6.5 V my expected 24 V are fine.

    Current is set up high enough to get the energie from the capacitor.

    Vin: 24V

    Vout: 10V…

  • LT8228 battery charge

    Dear Sir,

    I want to use LT8228 to design a powerbank with usb type c interface. The battery is 14S. Here I have some questions:

    1. Can I use the boost mode to charge the battery?  The battery connect to V1 and the VBUS of type C connect to V2. 

    2. How does…

  • Questions about LT8228

    Hi ADIExpert

    I have some questions about LT8228 application, may I have your suggestion for them

    1. How does LT8228 change CC to CV mode and vice versa? couldn't find the description in the datasheet.

    2. If I used 10 phases of LT8228 , and take each…

  • LT8228 simulation for boost mode

    Hi, ADI Engineer.

    I want to ask about how to switch boost mode in LT8228 in the simulation of LTSpice as currently, I want to test and see the simulation of LT8228 in boost mode by using its macro model's test fixture which is Buck 560W (14V 40A) and…

  • LT8228: Additional Circuitry for Programmable Output Voltage?

    Hello everybody,

    I want to be able to dynamically program the output voltage ofthe LT8228 from a MCU, across a large range from say 10V to 60V. For a Buck only design.

    I was thinking I could create an op amp gain stage between the voltage divider …

  • LT8228 question regarding V1 (high side) CSA stability

    Hello,

    I have a problem with a custom board designed using the LT8228 and stability of the V1 CSA.

    With no stability capacitor fitted (C12 in the section below) I cannot get the LT8228 to remain in operation.
    It will start switching and then shut down…

  • RE: Using LT8228 LTspice module as a subcircuit in a hierarchical schematic design?

    Hi, 

    Are you are trying to create a hierarchical block that contains the LT8228?

    If so, try to do the following steps:

    (1) Open the demo sim file for LT8228 and remove the input source and output load. 

    (2)  Add net names or labels to specific nodes that…
