Notice 1. Input / output capacitor When a inductance or a switch devise are connected to the input line, or when you use a power supply with output inductance as the input voltage source, the input voltage of the DC-DC Converter will be fluctuated. By this input voltage fluctuation, the transient load response of the DC-DC Converter may be deteriorated or abnormal oscillation may occur. So please confirm normal operation on each application. Please use external input capacitor in order to decrease inductance of input line. In case you use external output capacitor in order to improve transient load response, please use input capacitor to prevent abnormal oscillation. 2 Wiring of input / output capacitor In the case of input / output capacitor connection, in order to reduce electrical noise , please design PCBs with consideration of the following item. ①. Please be sure to check normal operation on your system. ②. Please use low impedance capacitors with good high frequency characteristic. ③. Please shorten those leads of each capacitor as much as possible, and make sure the lead inductance low. ④. Both input-side and output side, please make the wiring loop between plus and minus as small as possible. The influence of leakage inductance can be reduced. ⑤. Please design the print pattern of the main circuit as wide and short as possible..
