 Description
The LMZ14201 SIMPLE SWITCHER® power module
is an easy-to-use step-down DC-DC solution that can
drive up to 1-A load with exceptional power
conversion efficiency, line and load regulation, and
output accuracy. The LMZ14201 is available in an
innovative
package that enhances thermal
performance and allows for hand or machine
soldering.
The LMZ14201 can accept an input voltage rail
between 6 V and 42 V and deliver an adjustable and
highly accurate output voltage as low as 0.8 V. The
LMZ14201 only requires three external resistors and
four external capacitors to complete the power
solution. The LMZ14201 is a 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 into a prebiased output. A single
resistor adjusts the switching frequency up to 1 MHz.
