Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM3674MFX-ADJ

LM3674MFX-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM3674MFX-ADJ is a synchronous step-down DC-DC converter manufactured by Texas Instruments. It operates with an input voltage range of 2.7 V to 5.5 V and provides up to 600 mA of output current. The device utilizes a fixed switching frequency of 2 MHz, allowing for the use of small external components. It features an adjustable output voltage configuration and is housed in a SOT-23-5 package. The operational temperature range extends from -30°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Internal synchronous rectification ensures high efficiency during PWM mode operation.
Fixed-frequency Pulse Width Modulation (PWM) operation at 2 MHz minimizes external component size.
Shutdown mode reduces battery consumption to typical levels of 0.01 µA.

Voltage Regulators - DC DC Switching Regulators Applications

Mobile phones
Portable systems
Low-voltage circuits powered by single Li-Ion cell batteries

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'ADJ' against the official datasheet to confirm the adjustable output voltage variant. Ensure the package type matches the required SOT-23-5 footprint. Confirm RoHS compliance status as indicated in the manufacturer's documentation before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing portable electronics requiring a compact power solution. The 2 MHz switching frequency allows for smaller inductors and capacitors compared to lower-frequency alternatives. Ensure the load current requirements do not exceed the 600 mA limit across the full input voltage range.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM3674 series of step-down DC-DC converters. The series is optimized for powering low-voltage circuits from single-cell lithium-ion batteries. Other variants in the family include fixed output voltage versions such as 1.2 V and 1.8 V models.
