LTC3830ES

DC DC Switching Controllers Overview

The LTC3830ES8 is a high-power step-down synchronous DC/DC controller designed for low voltage operation. It operates from an input voltage range of 3V to 8V and supports output voltages from 600mV to 7.28V. The device features a fixed switching frequency of 500kHz and delivers up to 20A of output current with a single output configuration. Quiescent supply current is 700µA, while standby current is 10µA. It is available in an 8-pin SOIC package.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix (e.g., ES8#PBF or ES8#TR) to confirm packaging type and RoHS compliance. Confirm availability status as some variants may be discontinued or limited. Ensure the selected part matches the required thermal performance for the target application environment.

DC DC Switching Controllers Selection Notes

Select based on input voltage compatibility within the 3V to 8V range. Consider the 500kHz switching frequency for component size trade-offs. Verify that the 20A current capability meets load requirements. Check package availability against assembly constraints.

DC DC Switching Controllers Part Context

Part of the LTC3830 family of high-performance synchronous buck controllers. Designed for applications requiring efficient power conversion at low voltages. Shares architectural similarities with other members in the series but differs in pinout and specific electrical characteristics.

DC DC Switching Controllers Replacement Considerations

LTC3830ES8#TRPBF is a direct replacement variant differing primarily in tape-and-reel packaging compared to tube packaging.
