Description
Mini MP1584 Step-Down (Buck) Converter 3A – Fixed 3.3V Output
The Mini MP1584 Step-Down Module is a compact and efficient DC-DC buck converter designed to convert a wide input range of 4.5V to 28V into a stable 3.3V fixed output. With a maximum load capacity of 3A (recommended 2A continuous), it is ideal for powering ESP8266, ESP32, STM32, logic ICs, and 3.3V sensors. Operating at a high switching frequency of 1.5 MHz, the module ensures low ripple, high efficiency (up to 92%), and stable performance in embedded and portable applications.The module comes factory-calibrated for 3.3V output with no variable resistor, making it a true plug-and-play solution. It features over-current protection, thermal shutdown, and short-circuit safety to guarantee reliability. Its lightweight and compact size make it perfect for DIY electronics, robotics, IoT devices, and battery-based projects requiring a dedicated 3.3V regulated power source.
