DC-DC converters can be employed to alter the impedances presented to a load, as well as to convert voltages over wide ranges to meet the needs of specific applications. The 20IMX7-15-15-8M converter from Analog Devices is one such example. Its wide input voltage range, efficient current delivery, and advanced safety features make it well suited for applications with standard input voltage, current, and power requirements.

Features

The 20IMX7-15-15-8M DC-DC converter comes with a wide input voltage of 7.5 to 15V and an output voltage of 15V. It also provides an output current of up to 8A. The device features overvoltage protection and is equipped with an EMI filter to reduce electromagnetic interference. It has an integrated thermal shutdown circuit which helps to prevent any over-temperature conditions arising.

Applications

The 20IMX7-15-15-8M DC-DC converter can be used in a wide range of applications. These include powering devices such as automotive radars, vehicle control systems, medical imaging, as well as wireless equipment. It can be used in a variety of other applications too that require a wide input voltage range.

Working Principle

The 20IMX7-15-15-8M DC-DC converter works in a voltage-mode synchronous buck topology to step down its input voltage. This topology consists of two switches, an inductor, and a diode – the two switches being an NMOS and a PMOS. The NMOS switch is opened and closed alternately to control the output voltage. During the on-time of the NMOS switch, current is delivered from the input to the output through the inductor. When the NMOS switch is off, current is delivered from the inductor to the output through the diode. This way, an output voltage is created across the load and is regulated by varying the duration of the on-time of the NMOS switch.

Advantages

The 20IMX7-15-15-8M DC-DC converter offers a number of advantages, such as low power consumption, reliable overvoltage protection, and a wide input voltage range. It also offers an integrated EMI filter, which helps to reduce the amount of electromagnetic interference. The device is designed to work in harsh environments as it has an integrated thermal shutdown circuit which helps prevent over-temperature conditions. Finally, the 20IMX7-15-15-8M DC-DC provides efficient current delivery, making it an ideal choice for a range of applications.
