Application Guide
Ripple Removal Capability
We measured ripple voltage by oscilloscope for output capacitor change on the
typical chopper type DC-DC converter. (described below)
V OUT =5V, I OUT =0.5A
f=100kHz

Comparison Between
and Other Capacitors with Same Capacitance
Low Impedance Aluminum Capacitor
16V100uF ( φ 6.3x11L)
Δ V=156mV
Low ESR Tantalum Capacitor
16V100uF (7.3x4.3x2.9)
Δ V=76mV
FPCAP
16V100uF ( φ 8x11.5L)

Examination of Same Level Residual Ripple Voltage
To obtain same level of ripple voltage to FPCAP , Low Impedance Aluminum capacitor needs 16V3300uF,
even Low ESR tantalum capacitor needs 4 pcs. of same capacitance.
