MIC2810-4LSYML-TR Datasheet/PDFMIC2810-4LSYML-TR application field and working principle
The MIC2810-4LSYML-TR adaptive low-noise boost converter, which is manufactured by Micrel, is a high-performance, low-noise 4-phase LDO linear regulator. It has a low voltage setting range of 0.8V – 3.3V, and a high current operating range from 1A to 8A. MIC2810-4LSYML-TR has different features for different applications, such as low quiescent current, low output voltage ripple, and low on-time. It is well suited for low noise and high accuracy requirements applications.
Application Field
The MIC2810-4LSYML-TR is mainly used in portable—and often battery– operated systems, such as smartphones, tablets, laptops, and other electronic gadgets. MIC2810-4LSYML-TR is optimally suited for applications that demand a low quiescent current, like wearable medical devices, IoT sensors, Bluetooth Low Energy (BLE) applications, and portable battery chargers.
Working Principle
When the MIC2810-4LSYML-TR is enabled, it uses a fixed frequency alternating pulse width modulation (APWM) method to convert an incoming DC voltage into an adjustable DC voltage output. MIC2810-4LSYML-TR is a voltage regulator, meaning it reduces or maintains a voltage to a certain value by converting the applied input voltage into the desired level of output. It regulates the output voltage by alternating the width of the pulse resulting from switching the control transistor\'s conduction. The current is measured on the LDO, and then adapted using a low-bandwidth error amplifier. This method provides an accurate and reliable voltage regulation loop that helps to maintain the desired output voltage. It also provides the ability to adjust the average voltage while keeping the peak voltage within limits.
Conclusion
The MIC2810-4LSYML-TR adaptive low-noise boost converter is a high-performance, low-noise 4-phase LDO linear regulator which enables high accuracy applications and low noise requirements. It is suitable for a wide range of applications, such as portable medical devices and IoT sensors, because of its low quiescent current and low output voltage ripple. In addition, the regulator works by using a fixed frequency alternating pulse width modulation (APWM) method to convert an incoming DC voltage into an adjustable DC voltage output.
