Texas Instruments (LM3674MF-1.2/NOPB)Buck (Step Down) Switching Regulator

Buck (Step Down) Switching Regulator, Fixed, 2.7V-5.5V In, 1.2V And 0.6A Out, SOT-23-5

Product Overview
The LM3674MF-1.2/NOPB is a step-down DC-to-DC Converter optimized for powering low-voltage circuits from a single Li-ion cell battery and input voltage rails from 2.7 to 5.5V. It provides up to 600mA load current over the entire input voltage range. There are several fixed output voltages and adjustable output voltage versions. The device offers superior features and performance for mobile phones and similar portable systems. During the pulse width modulation (PWM) mode, the device operates at a fixed-frequency of 2MHz (typical). Internal synchronous rectification provides high efficiency during the PWM mode operation. In shutdown mode, the device turns off and reduces battery consumption to 0.01µA (typical). During the first portion of each switching cycle, the control block in the LM3674 turns on the internal PFET switch. This allows current to flow from the input through the inductor to the output filter capacitor and load.
