LM46000QPWPRQ1

Overview

The LM46000QPWPRQ1 is a DC/DC Switching Regulator in the family of PMIC – Voltage Regulators. This voltage regulator is an integrated switching regulator which is designed to convert an input voltage supply of up to 8V to a regulated output voltage up to 4V. The wide input voltage range, low noise switching frequency and low quiescent current ensures that the LM46000QPWPRQ1 is the ideal solution for high power applications.

Application Field

The LM46000QPWPRQ1 is designed for any application requiring an efficient voltage conversion such as Automotive, Audio, RF, and Power Supplies. It is particularly suitable for automotive and industrial applications, as the LM46000QPWPRQ1 is available in a wide temperature range and can operate over a wide input voltage range. The LM46000QPWPRQ1 is also suitable for consumer applications such as tablet computers and portable media players.

Working Principle and Features

The LM46000QPWPRQ1 adopts a multi-mode step-down architecture and allows the user to select the best compromise between efficiency, transient response and output ripple by selecting the appropriate frequency or on-time setting. The device employs two seperate outputs, one to indicate the output voltage, and the second to indicate the output current, thus allowing the user to adjust the output voltage and current to meet their application\'s requirements. These two signals can also be used to further optimise the system\'s efficiency, as output voltage and current information can allow the user to properly adjust the output voltage according to the load.

The LM46000QPWPRQ1 has many features which make it suitable for a wide variety of applications, such as:

• Optimised switching frequency for better efficiency
• Wide input voltage range
• Low quiescent current
• Low minimum on-time
• Up to 90% efficiency
• Power good output
• Soft-start circuitry
• 16-Lead Qfn Packaging

Conclusion

The LM46000QPWPRQ1 is an ideal choice for high power applications requiring efficient voltage conversion with a wide input voltage range, low noise switching frequency and low quiescent current. Its many features enable the LM46000QPWPRQ1 to satisfy a variety of applications, from Automotive and industrial applications to consumer electronics such as tablet computers and portable media players.
