    • Product Details

    The MAX1953 evaluation kit (EV kit) demonstrates two low-cost, buck-controller application circuits. The MAX1953 application circuit features an adjustable current limit. The 1MHz switching frequency renders a small footprint. The MAX1954 application circuit operates from a 3V to 13.2V input voltage range and is adjustable independent of the supply voltage. The MAX1954 switches at 300kHz and boasts 93% efficiency with the supplied components.

    This EV kit comes with the MAX1953 and MAX1954 evaluation circuits fully assembled and tested.
