External Input-Output Capacitor When a inductance or a switch devise are connected to Input line, and the transient response at the time of load sudden change of input power supply is bad, input voltage is greatly changed at the time of load sudden change of DC-DC Converter. Since the load response ability of DC-DC Converter may not be normally demonstrated by this influence, and DC-DC Converter may cause unusual oscillation in such a case, please connect an input capacitors. Applying external output capacitor, total output capacitance should be the following maximum external output capacitance or less. Maximum External Output Capacitance： 1000µF MAX 12.

Caution The above capacitance and electrical characteristics are guarantees on a condition in measurement circuit by using DC power supply. When you connect an input inductance or an input power supply which has an output inductance, please confirm the operation including nearby circuits. Because it has the possibility that a DC-DC Converter causes unusual oscillation. Input / output capacitor connections; in order to minimize noise, please consider the following items. ① Be sure to carry out a system characteristic check. ② Use a low impedance capacitor with good high frequency characteristics. ③ Shorten the leads of each capacitor as much as possible to minimize lead inductance. ④ Make the area of wiring loop small in the input and output line to minimize leakage inductance. ⑤ Shorten the length of PCB pattern and widen patterns for main circuit. Make winding loop small. Vin(+) Vin KN series Vin(-) Shorten the leads and pattern. Vout(+) Vout(-) Make winding loop small. Load Shorten the leads and pattern. Note: 1.
