The latest additions to the SIMPLE SWITCHER power module family drive high-output voltage applications in a variety of markets including industrial, communications infrastructure, and military. The LMZ14201H, LMZ14202H, and LMZ14203H provide the efficiency of a synchronous switching regulator with the simplicity of a linear regulator, eliminating the external inductor and complex layout challenges typical of switching regulator designs. The modules accept an input voltage rail between 6V and 42V and deliver an adjustable output voltage up to 24V. A single resistor adjusts the switching frequency. Pin-to-pin compatible with other family members, the modules integrate a shielded inductor and feature efficiency up to 97%. Available in seven-pin, 10.16 mm x 13.77 mm x 4.57 mm packages with exposed-bottom pads, prices for the LMZ14201H, LMZ14202H, and LMZ14203H are $6.50, $7.50, and $9.50 each 500, respectively.
