This DC/DC step-down voltage converter is based on MP1584, converting input voltage between 4.5V and 28V into a smaller voltage between 0.8V and 18V. It is capable of driving a 3A load with excellent line and load regulation.
 
Note: Input must be >1.5V higher than output! The chip will switch on high temperature protection mode when it experiences a high-power conversion. Without any cooling, it is able to output 3A current at 5V. But at higher output voltages, the current output capacity is lower than 3A, to a minimum of 2A.
 
FeatureS:

  • Wide 4.5V to 28V Operating Input Range
  • Up to 92% Efficiency
  • Programmable Switching Frequency from 100kHz to 1.5MHz
  • High-Efficiency Pulse Skipping Mode for Ceramic Capacitor Stable
  • Internally Set Current Limit without a Current Sensing Resistor
  • Cycle-by-Cycle Over Current Protection
  • Input Under Voltage Lockout
