LMZ14201HTZE/NOPB

The LMZ14201H SIMPLE SWITCHER power module is an easy-to-use step-down DC/DC solution that can drive loads up to 1A and features excellent power conversion efficiency, line and load regulation, and output accuracy. The LMZ14201H uses an innovative package that improves thermal performance and supports manual or machine soldering. The LMZ14201H supports an input voltage rail range from 6V to 42V and can provide a highly accurate adjustable output voltage as low as 5V. The LMZ14201H only requires three external resistors and four external capacitors to complete the power solution. The LMZ14201H is designed to be reliable and robust and has the following protection features: thermal shutdown, input under-voltage lockout, output over-voltage protection, short-circuit protection, output current limiting, and start-up capability for pre-biased outputs. A single resistor can adjust the switching frequency up to 1MHz.
