FAQs
What is LM2673S-ADJ?
The LM2673S-ADJ is an adjustable output voltage, step-down voltage regulator manufactured by Texas Instruments. It is designed to efficiently convert higher input voltages to a lower, regulated output voltage, making it suitable for a wide range of power supply applications.
How Does LM2673S-ADJ Work?
The LM2673S-ADJ operates by using a step-down switching regulator topology to regulate the output voltage. It efficiently converts the input voltage to the desired output level by controlling the duty cycle of the internal switch. This results in higher efficiency and lower power dissipation compared to linear regulators, especially for applications with a significant voltage drop.
How Many Pins does LM2673S-ADJ have and What are the Functions of the Pinout Configuration?
The LM2673S-ADJ is available in a 16-lead SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:
- VIN: Input voltage pin.
- FB: Feedback pin for setting the output voltage.
- SW: Switch pin for the internal power switch.
- GND: Ground pin.
- SS/TR: Soft-start/Tracking pin for adjusting the start-up characteristics.
- EN: Enable pin for turning the regulator on or off.
What are the Pros and Cons of LM2673S-ADJ?
Pros:
- High Efficiency: Provides higher efficiency compared to linear regulators, making it suitable for power-conscious applications.
- Adjustable Output: Offers flexibility in setting the output voltage to meet specific requirements.
- Compact Size: Comes in a compact SOIC package, suitable for space-constrained designs.
- Overload Protection: Includes features such as thermal shutdown and current limiting for added protection.
Cons:
- Switching Noise: May produce electromagnetic interference (EMI) due to the switching operation.
- External Components: Requires external components such as inductors and capacitors for proper operation.
- Complexity: Switching regulators may require careful design considerations for stability and performance.
Are There Any Equivalents/Alternatives to LM2673S-ADJ for Recommendation?
- The LM2596 from Texas Instruments is a similar adjustable step-down regulator commonly used in power supply applications.
- Alternatives to the LM2673S-ADJ include the LM2940 from Texas Instruments and the LM1117 from STMicroelectronics.
