Linear Technology's LTC1871EMS - High Efficiency, No RSENSE Boost Converter

The LTC1871EMS from Linear Technology is a versatile and powerful boost converter that is designed to cater to a wide range of applications requiring high voltage outputs from lower voltage sources. This efficient component operates without the need for a sense resistor (No RSENSE™), which simplifies the design and enhances efficiency.

At the heart of the LTC1871EMS is a constant frequency, current mode architecture which provides excellent stability and response to line and load changes. With an input voltage range of 2.5V to 36V, the LTC1871EMS is suitable for single or multiple cell battery-powered applications, as well as automotive and industrial power systems.

The device features a high 1.5A switch which allows it to deliver outputs as high as 60V. The frequency of operation is programmable via an external resistor or can be synchronized to an external clock through the SYNC pin, ranging from 100kHz to 500kHz. This flexibility allows designers to optimize the converter for efficiency, size, or required output power.

Furthermore, the LTC1871EMS has built-in features that enhance the safety and reliability of the system. These include programmable soft start to limit inrush current during startup, short-circuit protection, and thermal shutdown. Additionally, it has a Burst Mode operation which reduces quiescent current to just 110uA, thereby improving efficiency at light loads and extending battery life in portable applications.

The compact MSOP-10 package makes the LTC1871EMS an excellent choice for space-constrained applications. Its small footprint, combined with a minimal number of external components, leads to a reduced board space and a simplified design process. Whether it's for portable devices, telecommunications, or automotive applications, the LTC1871EMS is a robust and flexible solution that delivers performance and reliability.

In summary, the LTC1871EMS from Linear Technology is an advanced, high-efficiency boost converter that offers a wide input voltage range, high output voltage capabilities, and a host of features designed to ensure stable and reliable operation in a variety of demanding applications.
