When you use these ICs, consider the following issues;  
As shown in the block diagram, a parasitic diode is formed in each terminal, each of these diodes is not formed for  
load current, therefore do not use it in such a way. When you control the CE pin by another power supply, do not make  
its "H" level more than the voltage level of VIN pin.  
Set external components as close as possible to the IC and minimize the connection between the components and  
the IC. In particular, a capacitor should be connected to VOUT pin with the minimum connection. And make sufficient  
grounding and reinforce supplying. A large switching current could flow through the connection of power supply, an  
inductor and the connection of VOUT. If the impedance of the connection of power supply is high, the voltage level of  
power supply of the IC fluctuates with the switching current. This may cause unstable operation of the IC.  
Protection circuit may work if the maximum duty cycle continue for the time defined in the electrical characteristics.  
Once after stopping the output voltage, output will restart with soft-start operation. If the difference between input  
voltage and output voltage is small, the protection circuit may work.
