LTC1871IMS#TRPBF - Boost Converter from Linear Technology

The LTC1871IMS#TRPBF is a versatile, high voltage, current mode boost converter integrated circuit (IC) from Linear Technology, designed to meet the needs of a wide range of power supply applications. This IC is capable of generating a boosted output voltage from an input voltage that is lower, making it ideal for applications that require a high step-up ratio.

Featuring a wide input voltage range of 2.5V to 36V, the LTC1871IMS#TRPBF is suitable for use with a variety of input sources, including single-cell batteries, multi-cell batteries, and automotive inputs. The IC can produce an output voltage as high as 60V, which is adjustable via an external feedback resistor network.

The LTC1871IMS#TRPBF operates at a switching frequency that can be programmed between 100kHz and 1MHz, allowing designers to optimize the performance of their power supply for efficiency or component size. The higher frequency operation also enables the use of smaller inductors and capacitors, which can help reduce the overall footprint of the power supply on the PCB.

One of the key features of the LTC1871IMS#TRPBF is its current mode control, which provides excellent line and load regulation, as well as a fast transient response. It also includes a powerful 1.5A onboard switch, which eliminates the need for an external power MOSFET. This can simplify the design and reduce the bill of materials.

The LTC1871IMS#TRPBF includes several protection features such as overvoltage protection, overcurrent protection, and thermal shutdown, ensuring reliable operation under fault conditions. Additionally, it comes in a compact MSOP-10 package, which is suitable for space-constrained applications.

Linear Technology's LTC1871IMS#TRPBF is an ideal solution for designers looking to create efficient, high voltage boost converters for applications such as TFT-LCD bias supplies, portable electronics, distributed power systems, and pre-regulators for linear regulators.
