Unisonic Technologies P2576L 5.0V Step-Down Voltage Regulator

Product Title: UTC P2576 5.0V SMD DC-DC Step-Down Voltage Regulator

The UTC P2576 is a highly efficient step-down (buck) switching regulator that is capable of driving a 3A load. Its simplicity lies in the fact that it only requires a small number of external components, making it easy to use. This regulator features frequency correction and a fixed-frequency oscillator, and can operate with ordinary inductors, simplifying the design of switch-mode power supplies.

One of the unique features of the UTC P2576 is its ability to ensure output load conditions and a 10% increase in oscillator frequency. It also has an external shutdown and a standby current of only 50uA. For added protection, the output switch incorporates cycle by cycle current limitations and thermal shutdown under fault conditions.

Key Features:

1. Output Current: 3A
2. Input Voltage Range: 7V to 40V
3. Requires only 4 External Components
4. Very High Efficiency
5. TTL Shutdown
6. Low Power Standby Mode
7. Thermal Shutdown and Current Limit Protection
8. Internal Oscillator: 52kHz Fixed Frequency

The UTC P2576 is suitable for a variety of applications, including simple high-efficiency step-down regulators, efficient pre-regulators for linear regulators, on-card switching regulators, positive to negative converters (buck-boost), negative step-up converters, and power supplies for battery chargers.
