Overview
The LTC3310SIV#PBF is a high-performance, low-noise, and high-efficiency DC-to-DC converter from Analog Devices Inc. This monolithic step-down DC/DC converter is capable of providing up to 10A of output current from an input supply voltage range of 2.25V to 5.5V. It employs the Silent Switcher 2 architecture, which ensures ultralow EMI emissions and high efficiency, even at switching frequencies as high as 5MHz. The device features a constant-frequency, peak current mode control architecture for fast transient response and includes a 500mV reference for low voltage outputs. It also supports 100% duty cycle operation for low dropout and includes various protection features such as output overvoltage protection, thermal shutdown, and output short circuit protection.
