EN5396 PowerSoC
Input and Output Capacitors
The input capacitance requirement is 2X47uF for the EN5396QI. Altera
recommends that a low ESR MLC capacitor be used. The voltage rating should
rated high enough to provide adequate margin for your application. There is a
pre-tinned pad for one additional 1210 capacitor to experiment with input filter
performance.
The output capacitance requirement is approximately 100uF of capacitance.
The EN5396QI-E evaluation board comes populated with 5 x 22uF, 6.3V 1206
MLC capacitors. The 5 parallel capacitors provide for reduced ESR and hence
lower output ripple voltage. If a minimum footprint configuration is desired, the 5
x22uF capacitors can be replaced with 2X 47uF MLC capacitors.
NOTE: Capacitors must be X5R or X7R dielectric formulations.
NOTE: Please refer to product datasheet for specific recommendations.
