TPS65261: about Automatic Power Sequencing in 2ch out put situation

Tsukui Yusuke

Part Number: TPS65261

Hi team,

Could you tell me about TPS65261 automatic power sequencing?
Customer is trying to use only two Vout.
(One Vout is set to the OPEN state.)

Under that condition,
Can customers use automatic sequence mode?
Or,When using only 2 channels,
Should customer use external sequence mode?

Please tell me how to use the recommended pin processing method and sequence when only 2 Channel is used.

Best Regards,
Yusuke/Japan Disty

    Hi, Yusuke

    1. When using only 2 channels, the TPS65261 cannot support automatic sequence mode.

    2. The customer has to use different open drain logic to control ENx pin which can implement different power sequence.   

    3. For unused channel, please connect its EN pin to GND, the other related pins can be floating.
