illustrate

The LMZ14203H SIMPLE SWITCHER power module is an easy-to-use step-down DC-DC solution for driving with excellent power conversion efficiency, line and load regulation, and output accuracy of 3A load capacity. The LMZ14203H is an innovative package that improves thermal performance and welding robots or permits.

Input voltage rails between 6V and 42V are accepted LMZ14203H and provide low-adjustable, highly accurate output voltages up to 5V. The LMZ14203H requires only three external resistors and four external capacitors to complete the power solution. The LMZ14203H is a reliable, rugged design with the following protection features: thermal shutdown, input undervoltage lockout, output overvoltage protection, short-circuit protection, output current limiting, and allows entry into the start-up of the pre-biased output. A single resistor regulates switching frequencies up to 1MHz.
