LM3671MF-1.6

Voltage Regulators - DC DC Switching Regulators Overview

The LM3671MF-1.6 is a synchronous step-down DC-DC converter manufactured by National Semiconductor, now part of Texas Instruments. It operates with a fixed output voltage of 1.6V and supports a maximum output current of 600mA. The device features a switching frequency of 2MHz and accepts an input voltage range from 2.7V to 5.5V. It utilizes a SOT-23-5 package and includes automatic transition between PWM and PFM modes for optimized efficiency across load conditions.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates synchronous rectification to maximize conversion efficiency within a compact footprint.
Automatically switches between Pulse Width Modulation (PWM) and Pulse Frequency Modulation (PFM) modes based on load requirements.
Provides low quiescent current operation in light-load conditions to extend battery life in portable applications.

Voltage Regulators - DC DC Switching Regulators Applications

Portable electronic devices requiring efficient power management
Battery-powered consumer electronics systems
Embedded circuits utilizing single-cell lithium-ion or alkaline batteries

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the specific suffix matches the required lead-free status and packaging format. Confirm that the fixed 1.6V output aligns with your system design requirements before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.6V rail is needed from a 2.7V to 5.5V source. It is suitable for designs prioritizing small board space due to the SOT-23-5 package. Consider alternative models if adjustable output voltage or higher current capacity beyond 600mA is required.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM3671 family of high-efficiency step-down converters. It shares architectural similarities with other members like the LM3671MF-ADJ but differs in having a fixed internal feedback network set to 1.6V rather than allowing external resistor programming.
