Low-voltage regulators simplify modem, DSP designs

Santa Clara, Calif. – National Semiconductor’s LM2852, the first member of the company’s Simple Synchronous buck regulator family, is a high-frequency, step-down switching voltage regulator that can drive up to 2-amp loads with high line and load regulation for cable and xDSL modems, digital signal processors, DSPs, field programmable gate arrays (FPGAs), and set-top boxes. “These highly integrated synchronous switchers combine high-efficiency, low-voltage operation and low component count for simplified design,” said Paul Greenland, director of product marketing for the company’s Power Management group.
