Description: Replacement: None. We are no longer offering this IC as a standalone product. This page is for reference only.
The LMZ14203 is a new power module from National Semiconductor and part of their Simple Switcher series. This IC is an easy-to-use step-down DC-DC solution capable of driving up to a 3A load with exceptional power conversion efficiency, line and load regulation, and output accuracy. The innovative TO-PMOD-7 package enhances thermal performance and allows for hand or machine soldering; the pins are each spaced by 1.27mm (0.05").
The LMZ14203 can step-down an input voltage of up to 42V to produce a configurable output voltage between 0.8 and 6V, all at up to 90% efficiency. Only three external resistors, and four capacitors are required to produce a step-down output from the IC. In addition the LMZ14203 provides a number of other features, including: thermal shutdown, input under-voltage lockout, output over-voltage protection, short-circuit protection, output current limit, and allows startup into a pre-biased output.
