3A STEP-DOWN VOLTAGE

SWITCHING REGULATOR

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

* Input Voltage Range from 7V to 40V

* Requires 4 External Components

* Very High Efficiency

* TTL Shutdown

* Low Power Standby Mode

* Thermal Shutdown,

* Current Limit Protection

* Internal Oscillator: 52 kHz Fixed Frequency
