illustrate
The LMZ14203 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 an output accuracy of 3A load capability. The LMZ14203 is an innovative package that improves thermal performance and is allowed to weld the manipulator.
The LMZ14203 can accept input voltage rails between 6V and 42V and provide adjustable output voltages down to 0.8V with high accuracy. The LMZ14203 requires only three external resistors and four external capacitors to complete the power solution. The LMZ14203 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 allowing start-up of prebiased outputs. A single resistor regulates the switching frequency up to 1MHz.
