FAQs
What is LM2675M-ADJ?
The LM2675M-ADJ is a high efficiency step-down voltage regulator integrated circuit (IC) manufactured by Texas Instruments. It is a versatile and adjustable switching regulator capable of delivering up to 1A of output current with excellent line and load regulation.
How Does LM2675M-ADJ Work?
The LM2675M-ADJ operates by efficiently reducing a higher input voltage to a lower regulated output voltage. It utilizes a switching topology to achieve high efficiency and low heat dissipation compared to linear regulators. The adjustable feature allows flexibility in setting the output voltage based on the application requirements.
How Many Pins does LM2675M-ADJ have and What are the Functions of the Pinout Configuration?
The LM2675M-ADJ comes in a 16-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:
- VIN: Input voltage pin.
- GND: Ground pin.
- VOUT: Output voltage pin.
- FB: Feedback pin for setting the output voltage.
- ON/OFF: On/Off control pin.
- COMP: Compensation pin for loop stability.
- SS/TR: Soft-start/tracking pin.
- PGND: Power ground pin.
What are the Pros and Cons of LM2675M-ADJ?
Pros:
- High Efficiency: Switching regulator design offers high efficiency and low power dissipation.
