MAX1776 Evaluation Kit
General Description
The MAX1776 evaluation kit (EV kit) provides a +5.0V
output voltage from a +5.5V to +24V input source. It
delivers 500mA output current and operates up to
100% duty cycle at dropout. The MAX1776 is a step-
down switching regulator with an internal power switch.
The EV kit is a fully assembled and tested surface-
mount PC board. It can also be used to evaluate other
output voltages in the +1.25V to +23.5V range by
adding the feedback resistors and changing a jumper
setting.
