Adjustable Step-Down DC/DC Converter (1.0V - 17V/1.8A)

This product has been discontinued.

This 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：
