his DC/DC step-down voltage converter is based on MP2037, it converts input voltage between 4.5V and 23V into a smaller voltage between 1V and 17V, capable of driving a 1.8A load with excellent line and load regulation. Note: Input must be >1.5V higher than output. High current output, the inductance will be hot. Feature: Wide 4.5V to 23V Operating Input Range Up to 95% Efficiency Fixed 340KHz Frequency 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

Specification: Input Voltage: 4.5V-23VDC Output Voltage: 1V-17VDC Continuous Output Current: Max. 1.8A Perk Output Current: 3A Max. Efficiency: 95% Output Ripple: <30mV Switching Frequency: 340kHz Operating Temperature: -40℃ to +85℃
