Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM3671MFX-1.375/NOPB

LM3671MFX-1.375/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM3671MFX-1.375/NOPB is a fixed-output synchronous step-down DC-DC converter manufactured by Texas Instruments. It provides a fixed output voltage of 1.375 V with a maximum load current capability of 600 mA. The device operates from an input voltage range of 2.7 V to 5.5 V and utilizes a typical switching frequency of 2 MHz. It features automatic transition between Pulse Width Modulation (PWM) and Pulse Frequency Modulation (PFM) modes, achieving a typical quiescent current of 16 µA in PFM mode and a shutdown current of 0.01 µA. The component is housed in a compact SOT-23-5 package.

Voltage Regulators - DC DC Switching Regulators Feature Summary
