High-Voltage Start-Up IC
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. IR’s proprietary HVIC
technology provides robust operation from high
input voltage levels with simple yet flexible
features.
