5pcs JacobsParts MP1584 3.3V Fixed Output 3A DC Step Down Converter Buck Module 4.5-28V In

This ultrasmall buck stepdown voltage regulator is surprisingly powerful for its size Synchronous rectification is more efficient and creates less waste heat which allows it to reach current ratings found in regulators many times its size Despite the small size and low price, this power regulator delivers on its specs The output voltage is fixed at 33V and cannot be adjusted compared to adjustable regulators, the fixed output saves time and ensures accuracy Be careful not to exceed the input voltage or maximum output current Do not back feed power through the module Do not apply reverse polarity voltage33V fixed output nonisolated Dc buck voltage regulator, ultra small module 22x17x4mmgreat for microcontrollers like the ESP8266, devices designed for 2x AA batteries, and moreInput: 4528V, Output:33V, 3A Peak 15A SustainedEfficiency: Up to 92% (depends on the difference between input and output voltage) This module uses synchronous rectification, the most efficient power conversion available10MHz Switching Frequency, 30mV ripple (no load), MP1584 Ic
