Voltage Regulators - DC DC Switching Regulators datasheet and documents for LMR54406DBVR

LMR54406DBVR

Voltage Regulators - DC DC Switching Regulators Overview

The LMR54406DBVR is a synchronous step-down converter from Texas Instruments' SIMPLE SWITCHER family, housed in a SOT-23-6 package. It supports an input voltage range of 4 V to 36 V and delivers up to 600 mA of output current. The device features adjustable output voltages from 800 mV to 28 V with a fixed internal switching frequency of 1.1 MHz. Quiescent current is specified at 80 uA, and it operates within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated synchronous rectification for high efficiency in a compact footprint
Fixed 1.1 MHz switching frequency enables the use of small external components
Low quiescent current consumption enhances efficiency during light-load conditions

Voltage Regulators - DC DC Switching Regulators Applications

Battery-powered portable electronics
Industrial point-of-load regulation
Embedded system power distribution

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number including the DBVR suffix to ensure the correct SOT-23-6 package variant. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Cross-reference the manufacturer datasheet for specific handling and reflow profile instructions to maintain component integrity during manufacturing processes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a moderate 600 mA output current is required within a constrained board area. The 1.1 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Ensure the application input voltage remains within the 4 V to 36 V range and that thermal dissipation capabilities of the SOT-23-6 package are sufficient for the expected load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LMR544xx series of SIMPLE SWITCHER converters, designed for space-sensitive applications. It shares architectural similarities with the LMR54410 but offers reduced output current capability. The series emphasizes ease of design implementation through integrated feedback networks and protection features common to Texas Instruments' buck regulator portfolio.
