DC Switching Voltage Regulators

The LM2676SX-5.0/NOPB is a high-efficiency step-down (buck) switching regulator from Texas Instruments. This device is designed to provide a stable and regulated output voltage from a higher input voltage source. Here's a brief description, features, and applications of the LM2676SX-5.0/NOPB:

Description:

The LM2676SX-5.0/NOPB is a compact, high-efficiency synchronous step-down regulator that can operate from a wide input voltage range. It is available in a thermally-enhanced, leadless, space-saving SOT23-6 package. The device has a fixed 5.0V output voltage and is ideal for applications where space is limited, and high efficiency is required.

Features:

1. Fixed 5.0V output voltage.
2. Wide input voltage range (4V to 40V).
3. High efficiency (up to 96%) for improved power savings.
4. Synchronous rectification for reduced power losses and improved efficiency.
5. Thermal shutdown and over-current protection for enhanced reliability.
6. Small form factor (SOT23-6 package) for space-constrained applications.
7. Low quiescent current (40μA typical).
8. Low dropout voltage (600mV at full load).

Applications:

1. Portable electronics: Powering small portable devices like smartphones, tablets, and wearables.
2. Power banks: Regulating the output voltage for charging USB devices.
3. IoT devices: Providing stable power to low-power IoT devices and sensors.
4. LED lighting: Driving low-power LED circuits with regulated output.
5. Medical devices: Ensuring stable power supply for sensitive medical equipment.
6. Industrial control systems: Providing regulated power to microcontrollers and other control circuitry.
7. Automotive electronics: Powering various electronic components in vehicles.

The LM2676SX-5.0/NOPB is a versatile and efficient step-down regulator suitable for a wide range of applications where a stable 5V output is required from a varying input voltage source. Its high efficiency, small form factor, and built-in protection features make it an ideal choice for space-constrained and power-sensitive applications.
