The Analog Devices LTC3440EMS is a high-efficiency, fixed-frequency Buck-Boost DC-DC converter designed for applications where the input voltage can be above or below the output voltage. It operates from a 2.5V to 5.5V input and provides a regulated output from 2.5V to 5.5V, delivering up to 600mA of current. The switching frequency is programmable from 300kHz to 2MHz, allowing designers to optimize for efficiency or component size. Housed in a compact 10-pin MSOP package, it is ideal for battery-powered portable electronics, medical devices, and wireless sensors.
- Seamless Buck-Boost Operation: Maintains a regulated output even when the input voltage crosses the output voltage, ideal for battery-powered devices.
- High Efficiency: The synchronous rectification and low quiescent current maximize battery life in portable applications.
- Programmable Frequency: The 300kHz to 2MHz switching frequency allows optimization between efficiency and external component size.
- Compact Package: The 10-pin MSOP package is ideal for space-constrained designs.
Portable Battery-Powered Devices
In devices powered by a single Li-Ion cell (3.0V-4.2V), the LTC3440EMS maintains a regulated 3.3V output whether the battery is fully charged (4.2V) or nearly depleted (2.5V), ensuring consistent performance throughout the battery life.
Handheld Medical Instruments
For glucose meters or portable monitors, the buck-boost topology ensures a stable 3.3V or 5V rail from a 2xAA battery pack (2.4V-3.2V), providing reliable operation even as batteries discharge.
Wireless Sensor Nodes
When powered by a solar cell or energy harvester with varying output, the LTC3440EMS can efficiently convert fluctuating input voltages to a stable 3.3V for microcontrollers and RF transceivers, maximizing energy harvesting efficiency.
USB-Powered Peripherals
In USB devices that need a 5V rail but may be powered from a 3.3V supply, this converter can boost the voltage up to 5V, or buck it down when the input is higher, providing a universal power solution.
Portable Audio Players
For audio codecs and amplifiers requiring a clean, stable supply, the LTC3440EMS's high-frequency operation (up to 2MHz) allows for small external components, reducing board space and minimizing noise.
