The LTC3858EUH-2#PBF is a polyphase, synchronous step-down DC/DC switching controller that uses a constant frequency, current mode architecture. It is packaged in a thermally enhanced 16-lead MSOP or 28-lead HTSSOP surface-mount package. This product is designed to be a part of a cost-effective, high-efficiency power supply solution that contains one or two regulated outputs. It operates from input voltage ranges of 8V to 60V and can deliver up to 6A of output current. It is ideal for applications where the highest power density and efficiency are of utmost importance.

The LTC3858EUH-2#PBF integrates two highly integrated, independent, paralleled controllers and power switches with sophisticated control algorithms. This allows the user to unique control flexibility with each switch and enables the design of high performance, high power density multi-output architectures that provide optimum efficiency and low cost solution. The device has an advanced current-sense amplifier with peak current detection, allowing fast and accurate current analysis with minimal dead-time setting. This makes it easy to set up the switch and minimize possible overshoot.

The LTC3858EUH-2#PBF integrates a highly efficient buck regulator and is capable of transition frequencies up to 2.2MHz. It features a programmable soft-start and synchronous operation of two independent switches, as well as switching and latching fault protection. It also contains a low-noise, wide range voltage reference for low-noise and high accuracy. Independent switching of the two channels makes it possible to use the same component for dual output applications.

The LTC3858EUH-2#PBF is designed to provide up to 6A of output current at up to 80% efficiency over a wide range of input and output voltages. The device also contains protection features such as over-voltage, under-voltage and over-temperature, as well as over-current and short-circuit protection. The device is also capable of working with switching frequencies up to 2.2MHz, allowing for small footprint and high performances.

The LTC3858EUH-2#PBF is an ideal solution for applications that require high power density and efficiency, such as automotive, telecom, computing, and industrial systems. The device features a low-side current sense input and peak current detection, enabling fast and accurate current analysis, and is able to transition currents up to 6A. It is capable of operating with switching frequency up to 2.2MHz, which allows for a small footprint, and offers complete protection features like over-voltage, under-voltage and over-temperature, as well as over-current and short-circuit protection.

In conclusion, the LTC3858EUH-2#PBF is a highly integrated, synchronous step-down DC/DC switching controller that provides up to 6A of output current at up to 80% efficiency over a wide range of input and output voltages. It is designed for applications that demand minimum power loss and highest power density, such as automotive, telecom, computing, and industrial systems. It offers a cost-effective, efficient, and reliable solution that is suitable for high power density, high efficiency multi-output power supply design.
