illustrate

The LMZ12003 simple switching power module is an easy-to-use step-down DC-DC solution that drives up to 3A of excellent power conversion efficiency, line and load regulation, output accuracy and load capacity. The LMZ12003 is available in an innovative package that improves thermal performance and welding robots or allows.

The LMZ12003 can accept input voltage rails of 4.5V and 20V and provides adjustable output voltages as low as 0.8V and high accuracy. The LMZ12003 only requires three external resistors and four external capacitors to complete the power solution. The LMZ12003 is a reliable, robust design with the following protection features: thermal shutdown, input undervoltage lockout, output overvoltage protection, short circuit protection, output current limiting, and allowing entry into the start-up of the pre-biased output. A single resistor regulates switching frequencies up to 1MHz.
