LM3488: with out soft start

Keiju Nakano

Part Number: LM3488
Other Parts Discussed in Thread: LM5155

i did design SEPIC with LM3488 for UPS board,
but that need more quick startup for power source transient.
i want compatible IC without soft start , or adjustable.
is it in lineup?

Hi Keiju,

Thank you for using the LM3488 in your design.

Unfortunately, LM3488 does not appear to have adjustable soft-start.

I would recommend looking at the newer IC's, such as the LM5155. The LM5155 can be thought of as an upgrade to the LM3488 with lower quiescent current, higher efficiency, and more features than that of the LM3488 including adjustable soft-start.

Thanks,

Richard
