Silent Switcher® Solutions for EMI Compliance
Analog Devices Electromagnetic Interference (EMI) compliance is often mandatory and a critical design challenge for medical, automotive, test, and measurement equipment manufacturers. For example, if a device fails EMI compliance, it not only creates a long design cycle, it also increases cost as a result of re-design and re-evaluation for EMI compliance. To overcome these challenges, Analog Devices offers Silent Switcher® Architecture which minimizes the risk of problems caused by EMI, making µModule® Regulators and Discrete DC-DC ideal for noise-sensitive applications.

LTC3309A/B Synchronous Step-Down DC/DC Converters
Analog Devices LTC3309A/B Synchronous 6A Step-Down DC/DC Converters feature Silent Switcher™ architecture designed to minimize EMI/EMC emissions. LTC3309A/B Converters are ideal for applications such as optical networking, servers, telecom, and DC power systems. These small, high-efficiency, low-noise, monolithic synchronous converters operate from a 2.25V to 5.5V input supply. These regulators achieve fast transient response with small external components using a constant frequency, peak current mode control at switching frequencies up to 3MHz, and minimum on-time as low as 22ns. These ICs regulate output voltages as low as 500mV. The devices are available in a low profile 12-lead 2mm x 2mm x 0.74mm LQFN-12 package with an exposed pad for low thermal resistance.
