P2576

DESCRIPTION

As a step-down (buck) switching regulator, the UTC P2576

provides drives 3A load. The UTC P2576 are simple because it

only needs to use a minimum number of external components.

Frequency compensation and a fixes-frequency oscillator are

in it. UTC P2576 can perform with standard inductors, and

simplifying the switch mode power supplies’ design. UTC P2576

guarantees output load conditions and ±10% on the oscillator

frequency. Its external shutdown is included with 50μA standby

current. As well as thermal shutdown for full protection under

fault conditions, the output switch has cycle by cycle current

limiting.
