LTC3313EV#PBF

LTC®3313 is very small, low noise, monolithic step-down DC/DC converter capable of providing up to 15A of output current. The device employs the Silent Switcher architecture to achieve both low EMI and high efficiency at switching frequencies as high as 5MHz. For systems with higher power requirements, multiphasing parallel converters is readily implemented. It uses a constant frequency, peak current mode control architecture for fast transient response. A 500mV reference allows for low voltage outputs. 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. Application includes automotive/industrial/communications, servers, telecom power supplies, distributed DC power systems (POL), FPGA, ASIC, µP core supplies.
