L6926Q1 is a DC/DC switching regulator IC specifically designed to provide a regulated output voltage across a wide input range. It is specially suited for applications with high efficiency, such as automotive, mobile phones, PDA accessories, telecom, and computing applications.

Application Field

L6926Q1 is suitable for a wide range of applications, such as cellular phones, industrial control, computers and communication systems, automotive, power supply systems, battery operated devices, and other related applications.

This device can be used in applications that require high integration, low noise, and low power consumption. Its wide voltage range and high efficiency make it ideal for high-end portable applications. Additionally, the L6926Q1 supports a host of features, including output protection and short-circuit protection, overvoltage protection, and thermal protection.

Working Principle

The L6926Q1 is a low-dropout linear regulator designed to provide a constant output voltage with very low noise and low power consumption. This is achieved by using a series of MOSFETs in an internal circuit to regulate the input voltage to the required output voltage. When the input is greater than the output, the series of MOSFETs act as switches and allow the input current to pass through the internal circuit, which reduces the input voltage to the desired output voltage. When the input voltage is lower than the output voltage, the MOSFETs act as a linear regulator and pass current through the internal circuit, which keeps the output voltage at a constant level.

The L6926Q1 also provides overvoltage protection and short-circuit protection to ensure the safety of the system. The overvoltage protection monitors the input voltage and senses when the voltage has exceeded the prescribed limit and then shuts down the output. The short-circuit protection detects the presence of a short circuit between the input and the output and shuts down the output to prevent damage to the system.

Conclusion

The L6926Q1 is a high-efficiency DC/DC switching regulator IC specifically designed for applications that require a regulated output across a wide input range. Its features, such as overvoltage protection, short-circuit protection, and thermal protection, make it ideal for portable applications. The wide voltage range and high efficiency of the L6926Q1 make it a great choice for variety of portable applications.
