MP2303ADN-LF-Z Synchronous Buck Converter

The MP2303ADN-LF-Z is a high-efficiency, synchronous buck converter from Monolithic Power Systems (MPS). This device is designed to provide a compact and integrated solution for power conversion in a variety of applications, including industrial, automotive, and consumer electronics. Here are some key features and specifications:

1. Manufacturer: Monolithic Power Systems (MPS)
2. Package: SOIC-8, which is an 8-pin Small Outline Integrated Circuit package.
3. Maximum Output Current: Capable of delivering up to 3A of continuous load current.
4. Input Voltage Range: Operates with an input voltage range from 4.75V to 28V.
5. Output Voltage Range: Adjustable output voltage from 0.8V to 25V.
6. Switching Frequency: Fixed at 340kHz, which helps in designing the input filter and can reduce electromagnetic interference (EMI).
7. Efficiency: The device achieves high efficiency, up to 95%, in synchronous mode operation.
8. Protection Features: Includes over-current protection and thermal shutdown to safeguard the device from damage.
9. Soft-Start Function: Prevents inrush current at startup, reducing the risk of damage due to high initial current surges.
10. Low Quiescent Current: In shutdown mode, the supply current drops to 1μA, which is beneficial for battery-powered applications.
11. Integrated Power MOSFETs: Reduces the number of external components needed, simplifying the design and saving space on the PCB.
12. Package Dimensions: The SOIC-8 package has dimensions of 3.9mm x 2.9mm, making it suitable for space-constrained designs.

The MP2303ADN-LF-Z is an excellent choice for applications requiring high efficiency, high integration, and a wide input voltage range. Its fixed frequency operation simplifies EMI filtering and its integrated MOSFETs reduce the bill of materials (BOM) cost and board space requirements. This converter is ideal for use in battery-powered devices, where efficiency and space are at a premium.
