Recently, the LMR14020SSQDDARQ1 DC-DC switching regulator from Texas Instruments has been gaining popularity in the market. This high efficiency converter offers 2.5A current capabilities and unique features for IoT applications including overvoltage protection, undervoltage protection, automatic load switchover, and programmable advanced data logging. As its name implies, it is a true single-stage synchronous buck regulator that efficiently regulates output voltages between 0.8V to 5.5V while consuming low quiescent current. Overall, the LMR14020SSQDDARQ1 is the ideal choice for power management in space constrained, battery-operated applications.

The applications of the LMR14020SSQDDARQ1 DC-DC switching regulator primarily lies in battery-operated IoT applications such as wearables and industrial control systems. The high efficiency ensures that battery power is not wasted and the low quiescent current helps extends the life of the battery. Furthermore, the overvoltage protection, undervoltage protection and automatic load switchover features make it easy for developers to design battery-operated applications with high reliability. In addition to these features, the device also supports programmable advanced data logging which further enhances the flexibility of the applications.

The LMR14020SSQDDARQ1 DC-DC switching regulator works on the principle of buck-boost-boost. It uses two series coupled inductors to transfer energy from the input voltage to the output voltage. The two inductors combine to provide up to 5.5V of output voltage while keeping the input voltage within the device’s safe operating range. This allows the device to tolerate input voltage variation between 5.0V and 32V without affecting the output voltage performance.

The LMR14020SSQDDARQ1 also includes a high-efficiency self-biased logic-level synchronous controller for seamless operation. The controller automatically optimizes the multiple parameters of the device such as switching controller, clock-master, ramp compensation block, integrated fast-start circuit, and adaptive soft-start according to the desired output voltage. Furthermore, the device also features integrated over voltage protection and under voltage protection to protect the system from any unexpected conditions.

Overall, the LMR14020SSQDDARQ1 is the ideal choice for power management in battery-operated IoT applications. The high efficiency, low quiescent current and feature rich package make it suitable for small form factor applications. With its small size, low power consumption and ease of use, the LMR14020SSQDDARQ1 DC-DC switching regulator is a great choice for applications with high reliability and tight size constraints.
