The circuit was designed for a 7V to 24V battery range, but accommodates from 4.5V to 24V. Some parameters, such as load-transient response and maximum thermal load capability, may be degraded by going outside the 7V to 24V range. The continuous output current rating, based on worst-case MOSFET RDS(ON), heat sinking, and other thermal stress issues, is 5.5A at TA = +70°C.
This EV kit is a fully assembled and tested circuit board. It also allows the evaluation of the MAX1711.
