Boost PFC and SMPS Control IC

Features

Description

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.
