A Appendix - Rev.A EVM

A.1 Rev.A - Input and Output Capacitors
This appendix contains the information about the original Revision A TPSM82821EVM-080 and
TPSM82822EVM-080 EVMs which are now Revision B. The Revision A EVMs are no longer available for
purchase.
C3, shown in Figure A-6, is provided for an additional input capacitor. This capacitor is not required for proper
operation, but can be used to reduce the input voltage ripple.
C8 is provided for additional output capacitors. This capacitor is not required for proper operation but can
be used to reduce the output voltage ripple and to improve the load transient response. The total output
capacitance must remain within the recommended range in the data sheet for proper operation.
