产品概述
The LM3674MF-ADJ 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. 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). A high switching frequency of 2MHz (typical) allows use of only three tiny external surface-mount components, an inductor and two ceramic capacitors.
- Operates from a single Li-ion cell battery
