Product Details

The MAX20072 evaluation kit (EV kit) demonstrates the performance and behavior of the MAX20071 and MAX20072 low-voltage step-down switching regulators.

The MAX20072 high-efficiency switching regulator family delivers up to 1A load current from 0.5V to 3.8V. The device operates from 2.7V to 5.5V, making it ideal for on-board point-of-load and post-regulation applications. Total output error is less than ±1.5% over load, line, and temperature. It features fixed-frequency PWM mode operation, with a switching frequency of 2.2MHz. The high operating frequency allows for all-ceramic capacitor design and other small-size external components.

The device provides an enable input (EN) and a power-good output (PG). The output voltage can be preset at the factory to allow customers to achieve ±1.5% output-voltage accuracy without using expensive 0.1% resistors. Alternatively, the output voltage can be set to any customer value by using two external resistors at the feedback with 0.5V internal reference. The device offers factory-programmable spread-spectrum switching and soft-start time.

The MAX20072 includes overtemperature shutdown and overcurrent limiting and is designed to continuously operate from -40°C to +125°C chip temperature.
