the max17112 evaluation kit (ev kit) provides a proven design to evaluate the max17112 high-performance step-up dc-dc converter, which provides a regulated supply voltage for active-matrix thin-film transistor (tft) liquid-crystal displays (lcds).
the ev kit operates from a dc supply voltage of 4.5v to 5.5v and is configured to operate with a switching frequency of 1mhz. the high switching frequency allows the use of small, surface-mount components. the step-up switching regulator is configured for a 15v output and provides 600ma with a 4.5v input.
