capacitor selection Select equivalent series resistance (ESR) input capacitor suppress dissipation from ripple currents. Also select equivalent series resistance (ESR) output capacitor. variation inductor current causes ripple currents output capacitor which, turn, causes ripple voltages output equal amount variation multiplied value. output capacitor value significant impact operating stability device when used DC/DC converter. Therefore, FUJITSU MICROELECTRONICS generally recommends capacitor, larger capacitor value used ripple voltages suitable. VIN/VOUT voltage difference within output capacitor value recommended. Types capacitors Ceramic capacitors effective reducing afford smaller DC/DC converter circuit. However, power supply functions heat generator, therefore avoid capacitor with F-temperature rating 20%) FUJITSU MICROELECTRONICS recommends capacitors with B-temperature rating 20%). Normal electrolytic capacitors recommended their high ESR. Tantalum capacitor will reduce ESR, however, dangerous because turns into short mode when damaged. insist using tantalum capacitor, FUJITSU MICROELECTRONICS recommends type with internal fuse.
