The LMZ14203TZX-ADJ/NOPB is a SIMPLE SWITCHER® Power Module can drive up to 3A load with exceptional power conversion efficiency, line and load regulation and output accuracy. SIMPLE SWITCHER power module is an easy-to-use step-down DC-DC solution. It enhances thermal performance and allows for hand or machine soldering. The LMZ14203 can accept an input voltage rail between 6 and 42V and deliver an 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 LMZ14203 is a reliable and robust design with the following protection features thermal shutdown, input UVLO, output overvoltage protection, short-circuits protection, output current limit and allows start-up into a pre-biased output. A single resistor adjusts the switching frequency up to 1MHz.
