The LM3677LE-1.8/NOPB is a step-down DC-DC converter designed for ultra-low voltage applications, capable of delivering up to 600 mA load current from a single Li-Ion cell battery with an input voltage range of 2.7V to 5.5V. It features a fixed output voltage of 1.8V and operates at a typical switching frequency of 3 MHz, allowing for the use of small surface-mount components. The device includes automatic switching between PWM and PFM modes to optimize efficiency, with a typical quiescent current of 16 µA during light load conditions and a shutdown current of just 0.01 µA. The LM3677LE-1.8/NOPB is available in a compact 5-bump micro SMD package, requiring only three external components for operation. It also incorporates protections against current overload and thermal shutdown, making it suitable for applications in mobile phones, PDAs, and other portable devices.
