Part Number: TPS65262
Other Parts Discussed in Thread: TPS65263

Hello team,

I am not using LDO1and LDO2. What should I do for the unused pin below?

LVIN1, LVIN2

LOUT1, LOUT2

LFB1, LFB2

LEN1, LEN2

Also the capacitor value recommended for V7V pin is 10uF on the datasheet, however 1uF capacitor is used on the EVM.
Which capacitor value is recommended?

Best Regards,

Kei Kuwahara

    Hi Kei,

    (1) Thanks for reaching out! If you need to use LDO1 and LDO2, please disable LEN1 and LEN2 (pull low), others can be floating. BTW, if you only need 3 bucks, we would also recommend TPS65263 which has 3 bucks without LDOs. 

    (2) The recommended V7V cap is 10uF.

    Thanks!

    BRs
