The preceding circuit before leaving the factory. This series should power source must be able to provide for converter be tested under load(Figure 1). If you want to further sufficient starting current lp. decrease the input/output ripple, you can increase (Figure 2) low ESR. However, the capacitance should not be too high(Table 2).

Figure 1 Temperature Derating Graph Operating Temp.( C ) - CTRL Terminal When open or high impedance, the converter will work well; When this pin is ‘high’; the converter will shutdown; It should be noted that the input current should remain between 5-10mA,exceeding the maximum 20mA will cause permanent damage to the converter.
