illustrate
The LMZ12003 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 LMZ12003 is an innovative package that improves thermal performance and is allowed by welding manipulators.
The LMZ12003 accepts 4.5V to 20V input voltage rails and provides adjustable output voltages down to 0.8V with high accuracy. The LMZ12003 requires only three external resistors and four external capacitors to complete the power solution. The LMZ12003 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 to enter. A single resistor regulates the switching frequency up to 1MHz.
