Using the output voltage and the inductance value found in the inductor selection guide, step 1, locate the appropriate capacitor value and voltage rating. Use the 5-V section in the output capacitor table in Table 9. Choose a capacitor value and voltage rating from the line that contains the inductance value of 47 μH. The capacitance and voltage rating values corresponding to the 47-μH inductor are: • Surface mount: – 68-μF, 10-V Sprague 594D series – 100-μF, 10-V AVX TPS series • Through hole: – 68-μF, 10-V Sanyo OS-CON SA series – 150-μF, 35-V Sanyo MV-GX series – 150-μF, 35-V Nichicon PL series – 150-μF, 35-V Panasonic HFQ series The capacitor list contains through-hole electrolytic capacitors from four different capacitor manufacturers and surface mount tantalum capacitors from two different capacitor manufacturers. TI recommends that both the manufacturers and the manufacturer's series that are listed in the table be used. |
