• LT8357 Sepic


    I want to develop a power supply circuit using the LT8357.
    The output voltage is 5Vdc with a maximum output current of 2.5A.
    The input voltage is always above 8V but during start-up it could drop to 3V for about 20msec. 

    So I was thinking of using the…

    Hi sereza1981,

    Using the excel tool, the ADP1614 could be used but it can only provide up to 1.2A.

    You may also take a look at LT8357. LT8357 Datasheet and Product Info | Analog Devices. It should have an available model in LTpowerCAD.

    Hi Benedict,

    The closest boost I could find is the LT8357 (LT8357 Datasheet and Product Info | Analog Devices). It has a typical application with 75V/2A from 24V-55V input.

    This IC has an LTSpice simulation found on the link above that you can modify…
