The LMZ14203H SIMPLE SWITCHER® power module is an 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 LMZ14203H is available in an innovative package that enhances thermal performance and allows for hand or machine soldering.

The LMZ14203H can accept an input voltage rail between 6 V and 42 V and deliver an adjustable and highly accurate output voltage as low as 5 V. The LMZ14203H only requires three external resistors and four external capacitors to complete the power solution. The LMZ14203H is a reliable and robust design with the following protection features: thermal shutdown, input undervoltage lockout, 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.
