DescriptionThe LMZ14203 SIMPLE SWITCHER power modulean easy-to-use step-down DC-DC solution that can
drive up to 3-A load with exceptional power
conversion efficiency, line and load regulation, and
output accuracy. The LMZ14203is availablein an
innovative package that enhances thermal
performance and allows for hand or machine
soldering.
The LMZ14203 can accept an input voltage rail
between6V and42V and deliveran adjustable and
highly accurate output voltage as low as 0.8V. The
LMZ14203 only requires three external resistors and
four external capacitors to complete the power
solution. The LMZ14203isa reliable and robust
design with the following protection features: thermal
shutdown, input UVLO, output overvoltage protection,
short-circuit protection, output current limit, and
allows start-up intoa prebiased output.A single
resistor adjusts the switching frequencyupto1 MHz.
