Product Details

The MAX15053 evaluation kit (EV kit) provides a proven design to evaluate the MAX15053 high-efficiency, 2A, step-down regulator with integrated switches. The EV kit is preset for 1.8V output at load currents up to 2A from a 2.7V to 5.5V input supply. The IC features a 1MHz fixed switching frequency, which allows the EV kit to achieve an all-ceramic capacitor design and fast transient responses.
