LM2675LD-12/NOPB Integrated Circuits (ICs)

Introduction

The LM2675LD-12/NOPB is a step-down (buck) switching regulator integrated circuit (IC) from the Texas Instruments’ LDO® family. It is a DC-DC converter that is optimized for low power, low voltage applications with very low quiescent current. This chip requires fewer external components than traditional regulators, and its design does not sacrifice accuracy or stability.

Application Fields

The LM2675LD-12/NOPB can be used in a variety of electronic systems. Its low voltage and low current capabilities make it suitable for use in mobile phones and other battery-operated devices. It can be used to power a range of components in these devices including displays, radios, cameras, and processors. Furthermore, it can be used in computers, electronic toys, and any other application which requires a consistent supply of low voltage and low current.

Working Principle

The LM2675LD-12/NOPB operates in a pulse-width modulation (PWM) mode. It uses a small transformer to convert the input voltage into a higher voltage which is then stepped down by an inductor and a capacitor to the required output voltage. The voltage is regulated by varying the PWM duty cycle. The chip also has protection features such as overtemperature and overcurrent protection.

Technical Specifications

The LM2675LD-12/NOPB has the following features:

• Input voltage range of 3.2V to 24V
• Output voltage range of 0.8V to 22V
• Maximum output current of 1A
• Efficiency of up to 95%
• Quiescent current of 10 μA

Conclusion

The LM2675LD-12/NOPB is a highly efficient and cost-effective step-down (buck) regulator IC from the Texas Instruments’ LDO® family. It is suitable for a wide range of low power, low voltage applications, including those found in mobile phones, computers, and electronic toys. The chip operates in PWM mode and has protection features such as overcurrent and overtemperature protection. It also has an input voltage range of 3.2V-24V, an output voltage range of 0.8V-22V, and a maximum output current of 1A. Its excellent efficiency and low quiescent current make it a great choice for any low power, low voltage application.
