The LM3671MFX-2.5/NOPB is a high conversion efficiency, dual output, DC-DC switching regulator with integrated functionality. It is specifically designed for applications where a regulated output voltage is required from an unregulated input power source. This device can be used in many applications such as motor drive circuits, voltage converters, and power supply applications.

The LM3671MFX-2.5/NOPB supports input voltage range of 4.5V to 20V and provides two regulated output voltage, +2.5V(Max @ 500mA) and +5V(Max @ 200mA). It supports operating temperature range from -40℃ to +85℃, and offers high level of functionality including programmable slew rate, programmable soft-start time out, and over-current protection as well as under-voltage lock-out.

The LM3671MFX-2.5/NOPB has an integrated high-side MOSFET for the +2.5V output and the +2.5V output is capable of delivering up to 500mA of output current. The integrated high-side MOSFET has a low-est resistance of < 0.6Ω and is capable of operating from a wide input voltage range of 4.5V to 20V. The integrated low-side MOSFET for the +5V output has a very low on-resistance of 0.02Ω and can deliver up to 200mA of output current.

The LM3671MFX-2.5/NOPB offers a wide range of features such as programmable soft-start time, input over-voltage protection, and over-current protection. The LM3671MFX-2.5/NOPB utilizes a switching frequency that can range from 200kHz to 1MHz and also offers a wide range of output voltage accuracy with a maximum amplitude of ±2.5% and a minimum pulse-width of 30ns.

The working principle of the LM3671MFX-2.5/NOPB is straightforward. When an input voltage is applied, the device controls the conduction of the two integrated MOSFETs and re-circulates the load current through an inductor and a capacitor. This re-circulation reduces the input power by reducing the large input voltage and converting it into a higher output voltage.

The LM3671MFX-2.5/NOPB provides several benefits to users such as high efficiency, wide input voltage range and integrated protection features. It is suitable for a wide range of applications, including motor drive circuits, voltage converters and power supply applications. The device is designed to be compatible with a wide range of products, including power management, charge controllers and LED controllers.
