Applications
The IRS2505L is a control IC for PFC boost
converters operating in critical-conduction mode.
The IC incorporates a voltage feedback loop for
output voltage regulation combined with smart
zero crossing detection to control the gate drive
output without the need for a secondary inductor
winding. DC output over-voltage protection and
cycle-by-cycle over-current protection are also
included. Multi-functional inputs enable the
IRS2505L to perform all functions with only 5
pins.
Package Options
 Off-line power supply
 Electronic ballast
 LED power supply
