TPS65632: Pin treatment, when NOT using OUTP2 on TPS65632 etc.

Motoyasu Hattori

Part Number: TPS65632

Hi,
I have questions of TPS65632.  Could you please let us know.

*1.
"Figure 8. Typical Application Circuit" on datasheet [SLVSCY2A] P.13 is different from "Figure 1. TPS65632 EVM Schematic" on TPS65632 Evaluation Module [SLVUAL2] P.4.  In other words, SW1P's L value and SWP2's L value are different. Which circuit is correct?  Please let us know.
(I think SW1P's L value and SWP2's L value is opposite on EVM's schematics.) 

*2.
My customer does not use OUTP2.  On this case, could you please let us know how to do pin treatment as follows?

OUTP2 : Open
SWP2 : Open??
AIN : ??
C5 (100nF) : Need this capacitor?  Connect PVIN?

Thanks and best regards,
M.HATTORI.

    Hello Hatori-san,

    Figure 8 in the datasheet is the correct one.

    If customer does want to use OUTP2:

    EN (pin 8) should be GND

    OUTP2, SWP2 should be left open

    AVIN, PVIN should still be connected to VIN

    C5 should still be installed.

    Kind Regards,

    Liaqat
