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℃
