Maxim Integrated develops a wide range of products to support various power supply configurations from DC/DC & AC/DC (off-line) SMPS. MAX15022EVKIT+ evaluations board demonstrates the features of the MAX15022, which is a high-efficiency, monolithic synchronous buck regulator with current-mode control, a power stage optimized for low voltages, and a control stage optimized for high-side switching. Using the MAX15022EVKIT+, the user can evaluate the performance of the MAX15022 in various typical applications.

The MAX15022EVKIT+ is equipped with a MAX15022 IC and an external power supply. It also features two load terminals, four voltage measurement points, an adjustable output voltage range of 0.9 to 4.5 V, and an adjustable switching frequency from 100 kHz to 500 kHz. The board provides a simple solution for evaluating the device performance in a typical configuration.

The MAX15022 uses a synchronous buck topology, which is used to efficiently step down a higher voltage to a lower voltage. In this configuration, the power is transferred from an input voltage source to a load in two stages. First, a high-side MOSFET is used to step down the input voltage, and then a low-side MOSFET is used to step the voltage further down to the required output voltage.

The MAX15022 has a PWM switching frequency from 100 kHz to 500 kHz that can be adjusted to obtain a desired frequency. The MAX15022 also features programmable soft-start, which helps to ramp the output voltage gradually. The output voltage is also programmable and can be adjusted using the voltage adjust pin. This allows the user to regulate the voltage to optimize the power delivery to the load.

The control loop of the MAX15022 is a current-mode loop, which helps to provide better dynamic response and better line and load regulation. It also helps in reducing output voltage ripple, improving power efficiency, and simplifying external components selection. The MAX15022 also provides protection features like undervoltage lockout (UVLO), overvoltage protection (OVP), current limit, and thermal shutdown to ensure reliable power supply operation.

The MAX15022 is optimized for low voltage applications, as it has low quiescent currents and low on-resistance for both low-side and high-side devices. It is also suitable for automotive applications, as it is AEC-Q100 Grade 1 compliant. Overall, the MAX15022 is a high efficiency, monolithic synchronous buck regulator with low RDS(on) devices, current-mode control, and optimized power stage for low voltages.

The MAX15022EVKIT+ is designed to demonstrate the features of the MAX15022 in a typical application. It also enables the user to evaluate the device performance in various conditions. It can be used in industrial, automotive, and consumer applications, and is suitable for high-side switching. The MAX15022EVKIT+ is a simple solution that helps the user to quickly evaluate the performance of the MAX15022.
