LM2676SX-12/NOPB  

DC Switching Voltage Regulators

The LM2676SX-12/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 wide range of input voltages. Here is a description of the model, its features, and applications:

Description:

The LM2676SX-12/NOPB is a monolithic step-down switching regulator that integrates all the necessary components, including an inductor, to provide an efficient and compact solution for converting higher input voltages to a lower, regulated output voltage. It is available in a thermally enhanced, lead-free, and RoHS-compliant SOIC-8 package.

Features:

1. Wide input voltage range: 4V to 40V
2. Fixed 12V output voltage
3. High efficiency: up to 96% depending on input voltage and output current
4. Low quiescent current: 50µA (maximum)
5. Internal compensation for easy external component selection
6. Over-current protection (OCP) and thermal shutdown protection
7. Synchronous rectification for improved efficiency at light loads
8. Soft-start feature to minimize inrush current
9. Small form factor: SOIC-8 package

Applications:

1. Power supply for portable electronics and battery-powered devices
2. Voltage regulation in battery charging circuits
3. Voltage conversion for low-voltage applications, such as microcontrollers and sensors
4. Power management in IoT devices and wearable electronics
5. Voltage regulation for small LED lighting applications
6. Power supply for low-power industrial and medical equipment

The LM2676SX-12/NOPB is an efficient and versatile step-down regulator suitable for a wide range of applications where a stable and regulated 12V output is required. Its high efficiency, low quiescent current, and small form factor make it an ideal choice for space-constrained and power-sensitive applications.
