Promoting ease of use, the first three members of the
LMZ-series SIMPLE SWITCHER power module family promises to help system designers get their products to market faster. They offer the efficiency of a synchronous switching regulator with the simplicity of a linear regulator, eliminating the external inductor and layout challenges common to switching-regulator designs. The power modules allegedly simplify power supply design for FPGAs, microprocessors, DSPs, and other POL conversions. Patent-pending packaging keeps EMI at bay, enabling the modules to meet requirements of the EN55022 (CISPR22) Class B radiated emission standard. The LMZ10504 supports maximum load currents of 4A with an input voltage range of 2.95V to 5.5V while the LMZ12003 supports maximum load currents of 3A with an input voltage range of 4.5V to 20V. With an input voltage range of 6V to 42V, the LMZ14203 supports maximum load currents of 3A. Prices for the
LMZ10504,
LMZ12003, and
LMZ14203 are $7.10, $7.25, and $9.50 each/500, respectively. NATIONAL SEMICONDUCTOR CORP., Santa Clara, CA. (800) 272-9959.
