Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2674LDX-5.0

LM2674LDX-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2674LDX-5.0 is a step-down switching regulator manufactured by Texas Instruments, formerly National Semiconductor. It operates with an input voltage range of 8 V to 40 V and provides a fixed 5.0 V output at up to 500 mA. The device features a maximum switching frequency of 275 kHz and achieves 90% efficiency. It is housed in an LLP-14 package (PDSO14) and supports an operating temperature range from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated high-side switch for efficient step-down conversion
Fixed 5.0 V output configuration
Operates within a wide 8 V to 40 V input range

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for embedded systems
Battery-powered equipment power management
Industrial control system voltage stepping

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as Texas Instruments or National Semiconductor on the datasheet header. Confirm the suffix 'LDX' corresponds to the LLP-14 package and '-5.0' indicates the fixed 5.0 V output variant. Ensure the component meets the specified -40°C to +125°C operating temperature range requirements for your application environment.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5.0 V output is required from an input source between 8 V and 40 V. The LLP-14 package suits applications needing through-hole or surface-mount flexibility depending on board layout. Verify that the 500 mA load current requirement does not exceed the device's thermal limits under expected ambient conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM267x series of SIMPLE SWITCHER regulators. It shares functional similarities with the LM2674N but differs in packaging, utilizing the LLP-14 form factor instead of MDIP. The series is designed for general-purpose DC-DC conversion with integrated protection features.
