DESCRIPTION

The LM3671 step-down DC-DC converter is optimized for powering low voltage circuits from a single Li-Ion cell battery and input voltage rails from 2.7V to 5.5V. It provides up to 600 mA load current, over the entire input voltage range. There are several different fixed voltage output options available as well as an adjustable output voltage version range from 1.1V to 3.3V.

The device offers superior features and performance for mobile phones and similar portable systems. Automatic intelligent switching between PWM low noise and PFM low-current mode offers improved system control. During PWM mode, the device operates at a fixed-frequency of 2 MHz (typ.). Hysteretic PFM mode extends the battery life by reducing the quiescent current to 16 andmicro;A (typ.) during light load and standby operation. Internal synchronous rectification provides high efficiency during PWM mode operation. In shutdown mode, the device turns off and reduces battery consumption to 0.01 andmicro;A (typ.).
