Analog Devices Inc. LTC3313 | Datasheet Preview

The Analog Devices LTC3313 Step-Down Silent Switcher is a very small, low noise, monolithic step-down DC-to-DC converter capable of providing up to 15 amp of output current from a 2.25 to 5.5 volt input supply. The device employs the Silent Switcher architecture to achieve both low EMI and high efficiency at switching frequencies as high as 5 megahertz. For systems with higher power requirements, multiphasing parallel converters can be readily implemented. The LTC3313 uses a constant frequency, peak current mode control architecture for fast transient response. A 500 millivolt reference allows for low voltage outputs and 100% duty cycle operation delivers low drop out. Other features include a power good signal when the output is in regulation, a precision enable threshold, output overvoltage protection, thermal shutdown, a temperature monitor, clock synchronization, mode selection, and output short circuit protection. The AEC-Q100 qualified device is available in a compact 18-pin 3 by 3 millimeter LQFN package.
