Description
The MAX1774 evaluation kit (EV kit) is a fully assembled
and tested surface-mount circuit board that contains a
dual step-down switching converter with a backup converter
circuit and low-voltage detectors. The circuit is configured
for a main output voltage of 3.3V and a core output
voltage of 1.8V. The main output provides up to 1.5A, and
the core output provides up to 500mA of current.
Power for the circuit can be provided from a 3.65V to
5.5V DC source. The EV kit can be reconfigured for input
voltages up to 28V. The core's input can be powered
from the input source, or for higher input voltages, from
the main output. The EV kit circuit includes battery monitoring,
switchover, and backup, allowing automatic
backup operation.
The MAX1774 EV kit demonstrates low quiescent current
and high efficiency (up to 95%) for maximum battery life.
Operation up to 1.25MHz allows the use of tiny surfacemount
components.
