MAX1722EZK+T is a DC to DC switching regulator integrated circuit (IC), designed for automotive applications and strictly compliant with the JEDEC standards for AEC-Q100 qualification. This IC is typically used in power management, and it allows one to generate regulated output by switching a powerful MOSFET. The output voltage is adjustable within the range 0.5 volts to 5 volts, with its 2.5 volts fixed version.

This switching regulator is based on a current-mode control architecture, and uses the voltage mode control technique along with the high-speed MOSFET. In this system, it is easy to set the exact output voltage level with its 2.5 Volt reference voltage. Additionally, it is capable of generating output voltage up to 6.5 volts, or under 0.5 volts, depending on the configuration.

The principle behind this device is simple; the MOSFET is switched, which in turn rises the output voltage. As the output voltage approaches the reference voltage, the off-time of the switching increases, and the MOSFET is turned off permanently once it reaches the predetermined voltage. The output voltage is then maintained through the feeding of current from the internal charge pump.

MAX1722EZK+T is a robust device that is ideal for automotive applications, as it has numerous user configurable features. Some of its features include: low current shutdown and current limit, over temperature shutdown, soft-start, current feedback compensation, and external frequency synchronization.

The device also provides excellent output voltage ripple, with peak-to-peak voltage noise of less than 1mV. Moreover, the switching frequency of 2 to 6 MHz allows optimization of size and efficiency of the total system. Since the device is capable of delivering up to 1.6A output current, it is suitable for numerous applications in the automotive sector.

MAX1722EZK+T is a high performance, small package device designed for energy efficient and highly reliable operation in automotive applications. It is advanced in terms of regulating the output voltage and load current, and is especially suitable for high capacitive loads. In addition, it also offers comprehensive protection features like current limit, over-temperature and short-circuit protection, making it preferred choice for powering a variety of automotive electronics.
