DC Switching Voltage Regulators

The LM2676SD-5.0/NOPB is a high-efficiency step-down (buck) switching regulator from Texas Instruments. It is designed to provide a stable and regulated output voltage from a higher input voltage source. Here's a brief description of the model, its features, and potential applications:

Description:

The LM2676SD-5.0/NOPB is a member of the LM2676 family of synchronous buck regulators. It is a compact, high-efficiency solution for converting higher voltage input sources to a lower, regulated output voltage of 5.0V. The device is available in a surface-mount package, making it suitable for a wide range of applications where space is at a premium.

Features:

1. Output Voltage: It provides a fixed output voltage of 5.0V.
2. High Efficiency: The LM2676SD-5.0/NOPB offers high efficiency, typically over 90%, which is crucial for battery-powered applications to extend battery life.
3. Synchronous Rectification: It uses synchronous rectification, which reduces conduction losses and improves efficiency, especially at higher input voltages.
4. Wide Input Voltage Range: It can handle a wide range of input voltages, making it versatile for different power supply scenarios.
5. Low Dropout Voltage: It has a low dropout voltage, which means it can regulate the output voltage even when the input voltage is close to the output voltage.
6. Pulse Width Modulation (PWM): The device uses PWM for regulation, which allows for precise control over the output voltage.
7. Protection Features: It includes over-current protection, thermal shutdown, and under-voltage lockout to safeguard against fault conditions.
8. Small Form Factor: The device is available in a small-outline package (SOP-8), which is suitable for space-constrained designs.
