LTC1909-8EG#TRPBF

DC DC Switching Controllers Overview

The LTC1909-8EG#TRPBF is a demonstration circuit board featuring the LTC1909-8 synchronous current mode switching controller. It functions as a step-down DC/DC converter with an input voltage range of 7.5 V to 21 V. The output voltage is programmable between 1.3 V and 3.5 V, supporting up to 10 A of output current. Voltage selection is managed via a 2-wire SMBus interface that programs internal registers with one of two available 5-bit VID codes.

DC DC Switching Controllers Feature Summary

Synchronous current mode switching control architecture
SMBus interface for digital voltage programming
Dual 5-bit VID code configuration capability

DC DC Switching Controllers Applications

Demonstration of SMBus controlled power supplies
Evaluation of high-current step-down conversion
System integration testing for programmable voltage rails

DC DC Switching Controllers Procurement Notes

Verify the specific suffix EG#TRPBF against official Analog Devices documentation to confirm it denotes the demonstration circuit board rather than the standalone IC. Ensure compatibility with required SMBus protocols and validate that the 7.5 V to 21 V input range meets system requirements before procurement.

DC DC Switching Controllers Selection Notes

Select this unit specifically for evaluating the LTC1909-8 controller's performance in high-current applications. It is suitable for designs requiring digital voltage adjustment via SMBus. Verify that the 10 A output capability aligns with load demands and that the input voltage window covers the available supply rails.

DC DC Switching Controllers Part Context

This part belongs to the LTC1909 family of synchronous buck controllers designed for high-efficiency power conversion. The EG#TRPBF designation identifies it as a demonstration kit used for engineering validation. It provides a reference design environment for assessing the controller's dynamic response and thermal characteristics under load.
