This DC/DC step-down voltage converter is based on MP1584, it converts input voltage between 4.5V and 28V into a smaller voltage between 0.8V and 18V, capable of driving a 3A load with excellent line and load regulation.Â Â Note: Input must be >1.5V higher than output! The chip will jumper to high temperature protection mode when it work at a high-power conversion, without any cooling, it is able to output 3A current at 5V. But at higher output voltage, the current output capacity is lower than 3A, the minimum is 2A. Â Feature? Wide 4.5V to 28V Operating Input RangeÂ Up to 92% EfficiencyÂ Programmable Switching Frequency from 100kHz to 1.5MHzÂ High-Efficiency Pulse Skipping Mode for Ceramic Capacitor StableÂ Internally Set Current Limit without a Current Sensing ResistorÂ Cycle-by-Cycle Over Current ProtectionÂ Input Under Voltage LockoutÂ Â Specification? Input Voltage: 4.5V-28VDC Output Voltage: 0.8V-18VDC Continuous Output Current: Max. 3A Perk Output Current: 4A Max. Efficiency: 92% Output Ripple: ?30mV Switching Frequency: 100kHz to 1.5MHz Operating Temperature: -40? to +85? Dimensions: 22mm*17mm*4mm(l*w*h) Â Documents? MP1584 Datasheet
