Feature：
- 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

- Input Under Voltage Lockout
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.
