LM3671MF-2.8 DC-DC converter: Pinout, Specification, and Datasheet

LM3671MF-2.8 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 µA (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 µA (Typ.).

The LM3671 is available in SOT23-5, tiny 5-bump micro SMD and 6-pin LLP packages in leaded (PB) and lead-free (NO PB) versions. A high switching frequency of 2 MHz (Typ.) allows the use of tiny surface-mount components. Only three external surface-mount components, an inductor, and two ceramic capacitors are required.
