LT3580HMS8E#TRPBF - Boost/Inverting DC/DC Converter

The LT3580HMS8E#TRPBF is a versatile DC/DC converter from Linear Technology, designed to serve a wide range of power supply applications. This converter is capable of generating either positive or negative regulated outputs from a single input power source. It is particularly well-suited for applications that require a compact, high-efficiency, and reliable power solution.

This product comes in an MSOP-8 package, offering a compact footprint for space-constrained applications. The LT3580 can be configured as either a boost, SEPIC, or inverting converter, which allows for flexible design options to meet specific circuit requirements. It is capable of generating output voltages up to 36V in boost mode and down to -36V in inverting mode, with an input voltage range of 2.5V to 32V, making it a versatile choice for a variety of input sources.

One of the key features of the LT3580HMS8E#TRPBF is its internal 2A, 42V switch, which enables it to deliver substantial power with minimal external components. Additionally, it offers a quiescent current of only 700μA, which enhances its efficiency and makes it ideal for battery-powered applications. Its switching frequency is user-adjustable from 200kHz to 2.5MHz, allowing designers to optimize the converter for size, efficiency, or required operating frequency.

The device also includes several protective features to ensure reliable operation under different conditions. It has a soft-start function to minimize inrush current during startup, and thermal shutdown to protect against excessive heat. Furthermore, the LT3580HMS8E#TRPBF incorporates a unique 'Burst Mode' operation that maintains high efficiency at low output currents, which is critical for extending battery life in portable devices.

Overall, the LT3580HMS8E#TRPBF from Linear Technology is a highly flexible and efficient solution for generating regulated output voltages. Its robust design and range of features make it an excellent choice for power supply designs in industrial, automotive, telecommunications, and portable device applications.
