LMZ14203HTZ

TEXAS INSTRUMENTS  LMZ14203HTZ  电源模块, 42V, 3A, 7TOPMOD

The is a SIMPLE SWITCHER® 6 to 42V 3A high output voltage Power Module which is an easy-to-use step-down DC-DC solution that can drive up to 3A load with exceptional power conversion efficiency, line and load regulation and output accuracy. The LMZ14203HTZ can accept an input voltage rail between 6 and 42V and deliver an adjustable and highly accurate output voltage as low as 5V. The power module only requires three external resistors and four external capacitors to complete the power solution. This power module is reliable and robust in design with the following protection features thermal shutdown, input under-voltage 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.
