MAX1953 Evaluation Kit

General Description

Features

The MAX1953 evaluation kit (EV kit) demonstrates three

low-cost, buck controller application circuits. The

MAX1953 application circuit features an adjustable current

limit. The 1MHz switching frequency renders a small foot-

print. The MAX1954 application circuit operates from a 3V

to 13.2V input voltage range and is adjustable indepen-

dent of the supply voltage. The MAX1954 switches at

300kHz and boasts 93% efficiency with the supplied com-

ponents. The MAX1957 application circuit demonstrates
