MP2307 3A-23V -340Khz Synchronous Rectified Step-Down Converter

MP2307 3A-23V -340Khz Synchronous Rectified Step-Down Converter is a high-efficiency DC-to-DC buck converter module. It effectively steps down a higher input voltage to a stable, lower output voltage, providing a reliable power source for your electronic projects. Engineers and hobbyists use this module to power microcontrollers, sensors, and other components directly from a higher voltage source like a battery or power adapter. Its synchronous rectification design offers superior efficiency compared to older converters, minimizing heat generation and extending battery life.

Key Features:

• High Efficiency: Features synchronous rectification, achieving over 90% power conversion efficiency.
• Wide Input Voltage Range: Accepts a broad input voltage from 4.75V to 23V, accommodating various power sources.
• High Output Current: Provides a continuous output current of up to 3A, capable of powering demanding loads.
• Adjustable Output Voltage: A built-in multi-turn potentiometer allows you to precisely set the desired output voltage.
• Built-in Protection: Includes thermal shutdown and over-current protection to safeguard your connected devices and the module itself.
• High Switching Frequency: Operates at 340kHz, which allows for smaller inductors and capacitors, resulting in a more compact module size.
