Product Overview

The LM3673TL-1.5EV is an evaluation board for LM3673, a step down DC to DC converter that is optimised 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 350mA load current, over the entire input voltage range. The device offers superior features and performance for mobile phones and similar portable systems. The LM3673 uses intelligent automatic switching between PWM and PFM for better efficiency. During PWM mode, the device operates at a fixed frequency of 2MHz (typ). Hysteretic PFM mode extends the battery life by reducing the quiescent current to 16μA (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 0.01μA.
