LTC3440EMS Description

Short technical summary and product information.

The LTC3440EMS is a versatile DC-DC switching regulator manufactured by Analog Devices, designed for step-up and step-down voltage conversion. It utilizes a buck-boost topology, allowing it to efficiently regulate voltage whether the input is higher or lower than the desired output.

 

This device features an adjustable output voltage and can supply a current of up to 600mA. It operates with a nominal input voltage of 2.5V and supports a switching frequency range from 300kHz to 2MHz, enabling the use of small external components. The synchronous rectifier design enhances efficiency.

 

Packaged in a compact 10-MSOP surface mount configuration, the LTC3440EMS is suitable for space-constrained applications. It operates within a temperature range of -40°C to 85°C, making it reliable for various environmental conditions. Its adjustable output and robust performance make it a suitable choice for a wide array of power management designs.

 

Key specifications include its buck-boost function, adjustable positive output, and a maximum output current of 600mA. The device is designed for surface mounting, requiring appropriate PCB layout and soldering techniques for optimal performance.
