Smaller input capacitor may leads to an unstable operation of this product caused by input voltage fluctuation. Please check the proper operation of it on your product when smaller input capacitor is used. Using ceramic capacitors as input capacitor may cause an increase of output voltage, because input ripple current flows through the external input capacitor and wiring resistance. This phenomenon is affected by the position of external capacitors, the value of external capacitors and voltage difference between Vin and Vout. Using low-impedance electrolytic capacitor will ease this problem. Please check the proper operation of it on your product when ceramic input capacitor is used. MPDRX004S Vin Cin Vout Ripple current Rw×Irpl appears as additional output ripple voltage. Rw Wiring resistance 7. 5 Output External capacitor Ceramic capacitors are recommended as output external capacitor. Using ceramic capacitors, small output variation and small ripple voltage are realized. Output capacitor should be within 47uF to 1000uF. Output capacitor shall be placed near the output terminal. When using plural capacitors, please make sure to place a capacitor of at least 47μF near the output terminal, and place other capacitors near the load. When using LC output filter, please make sure to place a capacitor of at least 47μF near the output terminal. 8. Reliability 8 .1 Humidity According to JIS-C-0022. 40 土2°C, 90 to 95%RH, 100 hours.
