The LTC3111EMSE#PBF is a high-efficiency, multi-functional synchronous buck-boost DC/DC converter manufactured by Analog Devices Inc., which is also known as Maxim Integrated. This versatile integrated circuit (IC) is designed to efficiently regulate voltage levels in a wide range of battery-powered and low-voltage applications, offering compactness, high performance, and flexibility.

Key Features:

  • Buck-Boost Topology: The LTC3111EMSE#PBF employs a buck-boost topology, allowing it to regulate output voltage levels that are higher or lower than the input voltage. This flexibility makes it suitable for applications with varying input voltage sources or output requirements.

  • Wide Input Voltage Range: It accepts a wide input voltage range, typically spanning from 2.5V to 18V, enabling it to accommodate various input sources such as single or multiple-cell batteries, solar panels, and other power supplies.

  • High Efficiency: With its synchronous rectification architecture and low-resistance MOSFET switches, the LTC3111EMSE#PBF achieves high conversion efficiency, minimizing power losses and maximizing battery life in portable and energy-harvesting applications.

  • Programmable Output Voltage: The output voltage of the converter can be programmed within a certain range using external resistors, providing flexibility to adapt to different load requirements or system configurations.

  • Low Quiescent Current: In standby or shutdown mode, the LTC3111EMSE#PBF consumes minimal quiescent current, helping to conserve battery power and extend operating time in battery-powered devices.

  • Integrated Power Path Management: It features integrated power path management functionality, allowing seamless transition between input and output power sources, prioritizing the most efficient power source while ensuring uninterrupted operation.

  • Fault Protection Features: The IC incorporates various protection features such as input overvoltage protection (OVP), output overvoltage protection, overcurrent protection (OCP), and thermal shutdown, enhancing system reliability and preventing damage to the converter and connected components.

  • Small Footprint Package: Packaged in an MSOP-16 (Mini Small Outline Package) with exposed pad, the LTC3111EMSE#PBF offers a compact footprint and ease of integration into space-constrained PCB layouts, making it suitable for portable and handheld devices.
