Voltage Regulators - DC DC Switching Regulators datasheet and documents for LMR14030SDDA

LMR14030SDDA

Voltage Regulators - DC DC Switching Regulators Overview

The LMR14030SDDA is a SIMPLE SWITCHER step-down converter from Texas Instruments, housed in an 8-pin SO-PowerPAD package. It supports an input voltage range of 4 V to 40 V and delivers up to 3.5 A output current with adjustable output voltages between 800 mV and 28 V. The device operates at a fixed switching frequency of 2.2 MHz and features a quiescent current of 40 uA. It functions within a junction temperature range of -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated power switch enables compact design for high-density applications
Fixed 2.2 MHz switching frequency minimizes external component size
Low quiescent current improves efficiency during light-load conditions
Built-in thermal shutdown protects against overheating

Voltage Regulators - DC DC Switching Regulators Applications

Industrial point-of-load regulation
Battery-powered equipment power management
Distributed power systems
Embedded computing subsystems

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'SDDA' corresponds to the tube packaging variant rather than tape-and-reel configurations like 'SDDAR'. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when a fixed 2.2 MHz frequency is required to optimize passive component footprint. Ensure the 3.5 A continuous current rating meets peak load demands while maintaining adequate thermal headroom within the specified operating temperature range.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LMR14030 series of non-synchronous buck converters. It shares architectural similarities with the LMR14020 (2 A) and LMR14050 (5 A) variants, offering scalable current capabilities within the same 40 V input family.
