„ 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.
„ FEATURES
* Output Current 3A

* Requires 4 External Components
* Very High Efficiency
* TTL Shutdown
* Low Power Standby Mode
* Thermal Shutdown,
* Current Limit Protection
* Internal Oscillator: 52 kHz Fixed Frequency
