Low EMI, Silent Switcher® Step-Down μModule Regulators from Linear Technology.
Reduce EMI and Improve Efficiency with Silent Switcher Designs. Silent Switcher architecture designed to minimize EMI/EMC emissions while delivering high efficiency. The monolithic construction with integrated power switches and inclusion of all necessary circuitry yields a solution with a minimal PCB footprint. An ultralow quiescent current—with the output in full regulation— enables applications requiring highest efficiency at very small load currents. Transient response remains excellent and output voltage ripple is below 10mVP-P at any load, from zero to full current. EN55022 Class B Certified CISPR 22 Class B Compliant, or CISPR 25 Class 5 Compliant.
