EN5336QI Evaluation Board Application Note
December 2006 V_1
Input and Output Capacitors
The input capacitance requirement is 22uF for the EN5336QI. Enpirion
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 50uF of capacitance. The
EN5336QI-E evaluation board comes populated with 5 x 10uF 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 x10uF
capacitors can be replaced with a single 47uF MLC capacitor.
NOTE: Capacitors must be X5R or X7R dielectric formulations. Do not use Y5V
dielectrics for input or output filter capacitors. Y5V capacitors lose capacitance
with bias voltage, temperature, and frequency, and are not suitable for this
application.
NOTE: Please refer to product datasheet for specific recommendations.
