PMIC - Voltage Regulators - DC DC Switching RegulatorsThe LM25018SDE/NOPB is a member of Texas Instruments\' family of Pulse-Width Modulator (PWM) voltage regulators specifically designed for DC-to-DC switching applications. Offering flexible step-up/step-down voltage conversion, this high-efficiency, single-output device operates with an input voltage of up to 32 V and is capable of providing up to 15 W of continuous output power in either step-up or step-down configurations.It has a wide range of features that enable it to be used in a variety of different types of applications, such as automotive, telecom, consumer, industrial, and aerospace applications. Additionally, its small size (8 mm × 8 mm) and low power dissipation (1.1 mW in shutdown) makes it an ideal choice for portable electronic devices with limited board space.The functional principle of LM25018SDE/NOPB voltage regulator is simple to understand. The device works by pulse-width modulation of the input voltage, wherein an output voltage is regulated through a feedback loop. This feedback loop operates in such a manner that when the output voltage drops below the desired voltage, the PWM cycle is increased to increase the output voltage. Conversely, when the output voltage rises above the desired voltage, the PWM cycle is decreased to decrease the output voltage.In addition to this basic control mechanism, the LM25018SDE/NOPB provides several configurable properties which help the user adjust the device to suit conditions of their application. This includes the capability to adjust both the PWM frequency and duty cycle, as well as the output voltage to optimize efficiency and reduce component count for an optimal power solution.The LM25018SDE/NOPB also features a number of protection features, such as over-voltage and thermal shutdown protection, as well as an adjustable soft-start circuit. This feature reduces the inrush current when the device is first powered on, thus protecting against excessive startup current.Overall, the LM25018SDE/NOPB is an ideal choice for many different types of voltage regulator applications. Not only does it offer reliable performance and high efficiency, but its comprehensive feature set and ease of use makes it a cost-effective and user-friendly solution that can be used in a wide range of applications.
