LTC3401EMS

The LTC3401EMS is a high-efficiency, synchronous step-down DC/DC converter designed by Linear Technology (now part of Analog Devices). It is tailored for battery-powered applications requiring compact size and low power consumption, such as cellular phones, PDAs, and handheld devices.
Operating at a fixed frequency of 3MHz, the LTC3401EMS utilizes a current mode, constant frequency architecture that allows for low noise operation and fast transient response. It can deliver up to 600mA of output current while maintaining high efficiency across a wide load range. The device operates from an input voltage range of 2.5V to 5.5V, making it suitable for single-cell lithium-ion battery power sources.
Key features include an adjustable output voltage, typically from 0.8V to the input voltage, internal synchronous switches to minimize external component count, and a shutdown mode reducing the supply current to less than 1µA. Its MSOP package ensures a small footprint, and the device also incorporates internal frequency compensation, soft-start, and over-temperature protection for enhanced reliability.
