Description

The IRS25751 is a 480V high-voltage start-up

IC ideal for supplying initial supply starting current

from a high-voltage bus. The IRS25751 supplies

a constant current during start-up and then

consumes

ultra-low

standby

(off)

current.

Additional features include programmability of the

upper turn-off threshold, an ENN input, and over-

temperature protection. I

R’s proprietary HVIC

technology provides robust operation from high

input voltage levels with simple yet flexible

features.
