MP2338 DC-DC Buck Converter – Up to 24V Input, 5V 3A Output
The 7Semi MP2338 DC-DC Buck synchronous converter breakout is a compact and efficient step-down power module designed to convert input voltages up to about 24V into a stable 5V output with up to 3A current. It is based on the MP2338 synchronous buck converter, which uses integrated MOSFETs to provide high efficiency and reliable power conversion. The module includes built-in protection features such as thermal shutdown and cycle-by-cycle current limiting to help protect the circuit during operation. Its small size and simple breakout design make it easy to integrate into power systems that require a stable 5V supply. This converter is suitable for powering 5V electronics, sensors, communication devices, control circuits, and other low-voltage systems where efficient and reliable voltage regulation is required.
Features
- Wide Input Range: Operates from DC 4.5V to 28V, making it versatile for various applications.
- Output: 5V 3A DC
- High Efficiency at Light Load: Power Save Mode ensures minimal energy loss during low power consumption, optimizing efficiency.
- Fast Transient Response: Constant-on-time (COT) control offers quick response to changes in load, maintaining steady output.
- 450kHz Switching Frequency: Ensures compact component size and smooth operation without excessive heat generation.
- tON Extension: Improves dropout performance for consistent voltage output under low input conditions.
- Adjustable Soft-Start: Configurable soft-start time reduces inrush current at startup, protecting sensitive components.
