The device is designed to be a high-efficiency, low-voltage, low-noise, low-power switching regulator capable of operating over a wide range of input and output voltages. In addition, it offers significant power savings by providing an adjustable peak-current limit and programmable switch-over frequency.

The MAX1522EUT+T provides the following features:

• High efficiency: With an efficiency of 95% at 100 kHz switching frequency and 95% at 250 kHz, the MAX1522EUT+T delivers significant power savings.
• Wide input-voltage range: The device operates between 3.3V to 20V, allowing it to be used with various input sources.
• Versatile output voltage settings: The output voltage can be adjusted between 0.9V and the input voltage, making it ideal for a variety of applications.
• Adaptive peak-current limit: The peak-current limit can be adjusted to match the specific application needs, allowing for more efficiency and longer system life.

The MAX1522EUT+T uses a synchronous buck topology, with an N-channel MOSFET switch and a single-phase, non-isolated, buck DC/DC controller IC. When the voltage across the switch is higher than the output voltage, the IC starts turning on the MOSFET. This causes the switch to open, and the inductor current flows through the diode and charges the output capacitors. When the switch is turned off, the current stored in the inductor is returned to the output following the diode. In this way, the output voltage is regulated by the switch voltage and cotrolled with the internal PWM controller.

The MAX1522EUT+T is an extremely versatile and highly efficient device, providing users with a wide range of input and output voltages and an adjustable peak-current limit, making it an ideal choice for a variety of power-supply applications.
