LMZ14201 SIMPLE SWITCHER power module is an easy-to-use step-down driving DC-DC solution with excellent power conversion efficiency, line and load regulation, output accuracy 1A load. LMZ14201 is an innovative solution that enhances thermal properties and allows for manual or machine welding.
LMZ14201 can accept input voltage rails between 6V and 42V and provide adjustable and highly accurate output voltages as low as 0.8V. LMZ14201 only requires three external resistors and four external capacitors to complete the power solution. LMZ14201 is a safe, reliable, and powerful design with the following protection features: thermal shutdown, input undervoltage lockout, output overvoltage protection, short circuit protection, output current limiting, and allows entry into pre-biased output start-up. A single resistor regulates switching frequencies up to 1 MHz.
