LM3674MFX-1.8/NOPB

LM3674为2MHz ，采用SOT -23 600mA降压DC- DC转换器 LM3674 2MHz, 600mA Step-Down DC-DC Converter in SOT-23

The LM3674 step-down DC-DC converter is optimized for powering low-voltage circuits from a single Li-Ion cell battery and input voltage rails from 2.7 V to 5.5 V. It provides up to 600-mA 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 2 MHz typical. Internal synchronous rectification provides high efficiency during the PWM mode operation. In shutdown mode, the device turns off and reduces battery consumption to 0.01 µA typical.

The LM3674 is available in a 5-pin SOT-23 package. A high switching frequency of 2 MHz typical allows use of only three tiny external surface-mount components, an inductor and two ceramic capacitors.
