LMZ14203HTZE/NOPB Datasheet PDF - TI

●The LMZ14203HTZE/NOPB is a SIMPLE SWITCHER® high output voltage Power Module can drive up to 3-A load with exceptional power conversion efficiency, line and load regulation and output accuracy. The power module is an easy-to-use step-down DC-DC solution. It enhances thermal performance and allows for hand or machine soldering. The LMZ14203H can accept an input voltage rail between 6 and 42V and deliver an adjustable and highly accurate output voltage as low as 5V. The LMZ14203H only requires three external resistors and four external capacitors to complete the power solution. The LMZ14203H is a reliable and robust design with the following protection features thermal shutdown, input undervoltage lockout, output overvoltage protection, short-circuit protection, output current limit and allows start-up into a pre-biased output. A single resistor adjusts the switching frequency up to 1MHz.
