Features
Key features include a fixed 260 kHz switching frequency, which balances efficiency and size, and a built-in cycle-by-cycle current limit to protect against overloading. The LM2676SX-5.0 also offers thermal shutdown to prevent damage from overheating. Its simple design requires minimal external components, aiding in compact PCB layout and reducing overall BOM costs.
The regulator comes in a TO-263 surface-mount package, which is suitable for automated assembly. It also includes an on/off control function to enable low-power standby mode. The device is designed for ease of use in applications like battery-powered devices, industrial equipment, and automotive systems.
Pinout
1. Vin (Pin 1): This is the input voltage pin. It accepts a wide range of input voltages and supplies power to the device.
2. SW (Pin 2): The switch pin is connected to the internal power switch. It is used for connecting the inductor and is part of the switching regulator's output path.
3. GND (Pin 3): This is the ground pin, which serves as the reference point for the circuit and is essential for stable operation.
4. FB (Pin 4): The feedback pin is used to provide output voltage regulation by connecting it to the output through a resistor divider.
5. Boost (Pin 5): This pin is used to provide a higher voltage to the internal power switch for efficient operation.
The LM2676SX-5.0 is commonly used in applications requiring efficient step-down voltage conversion with minimal external components.
