MAX17290ETCF+T is a highly integrated buck (step-down) switching regulator for direct current (DC) to DC voltage conversion applications. It offers high efficiency, excellent load transient response, and small size. It is suitable for wide range of input and output voltages and provides high power density. The device works from a wide input voltage range of 8V to 125V, with an output voltage range of 0.7V to 12V. The peak current of the device can be up to 350mA, its efficiency up to 90%. The MAX17290ETCF+T includes a built-in internal power MOSFET, internal current sensing and voltage feedback, as well as an overcurrent protection circuit.

The MAX17290ETCF+T is designed for adjustable input and output. The device can adjust the output voltage level on-the-fly using the voltage-mode control. This allows for a variable voltage output to correspond to the input voltage, thus providing a way for designers to optimize the power conversion efficiency for a given load and input voltage range. For example, if the input voltage is 15V, the device can adjust its output voltage up to 12V, thus providing up to 80% conversion efficiency.

The MAX17290ETCF+T also includes a mobile power companion circuit which enables the device to operate with a wide range of input and output voltages. The mobile power companion circuit monitors the input voltage and cycles the power MOSFET accordingly. The power MOSFET is cycled to boost the input voltage, thus converting the input voltage to a desired output voltage while also providing an improved power conversion efficiency.

The MAX17290ETCF+T utilizes current-mode control to enable fast transient response, low output voltage ripple and improved power conversion efficiency. The device uses a fixed off-time and current-limit control to ensure robust and reliable operation. The switching frequency is programmable from 1kHz to 5 MHz, which allows designers to tailor the performance of their system to fit the application requirements. The device also integrates a variety of protection features, including overvoltage protection, overcurrent protection, undervoltage protection, and thermal shutdown to protect the device from overloading and over-temperature.

The MAX17290ETCF+T is suitable for a wide range of applications, such as consumer electronic devices, medical equipment, industrial systems, and motor control, which require high efficiency and excellent load transient response. This device is a great choice for those who need a quick and efficient power conversion solution.
