TPS92682-Q1: Unused Pin

user6526132

Part Number: TPS92682-Q1

(1) There are 2 channels, but please tell me how to handle the terminals if 1 channel is unused.

(2) This is a 2ch product, but is there an equivalent 1ch product?

Hello,

I don't fully understand your question here. But here's an attempt.

1. If there are 2 channels on the board and if you do not use one channel then you just don't enable that channel in the EN register.

2. I really don't understand what you are asking here please give more details.

Thanks Tuan

thank you for your reply.

(1) channel-2 is not used. Is it okay to leave related pins GATE2, ISP2, FB2, COMP2, FLT2, and PWM2 open?

　Is terminal processing such as pull-down required?

(2) "Single-Channel Constant-Voltage and Constant-Current Controller Do you have parts for "with SPI Interface"?

Hello,

1. Yes, it's ok to leave GATE2, ISP2, FB2, COMP2, FLT2 and PWM2 open. In addition, you need to verify that CH2EN is also set to 0 for disabled.

2. Currently we only have the TPS92682 an SPI interface part and not a single channel part.

Thanks Tuan
