LM66200: datasheet does not directly indicate which Vout is connected to which Vin?

Steve Wenner

Part Number: LM66200
Other Parts Discussed in Thread: TPS61033, LM66100

Tool/software:

1. Can someone tell me which Vout pin on this part corresponds to Vin1 and which Vout pin corresponds to Vin2? This is not indicated in datasheet and I would like to use the ideal diodes independently without joining the Vouts.

2. I will be connecting a battery on Vin1 (3.2V - 2.2V). I will be connecting TPS61033 Boost converter to Vin2. I will be enabling the boost converter at various times. The ON is tied low so that the output will always be enabled. I am looking for a sanity check here, can you foresee any reason that this might not work at switching back and forth between Vin1 and Vin2?

Sincerely

Steve

Hi Steve,

1.VOUT is common for both the inputs.

Since you want an uninterrupted VOUT, you will be connecting two different VOUTs (if available) together, right?

2. Yes, you can use this controller, and the system will work fine.

Hello Shiven.

Thank you for the response. Yes I understand but can you please find out from the engineering team if these are available as single diodes and NOT connected internally? And if so then what pin on Vin corresponds to what Vout? I may want to independently use these WITHOUT the connection you show as a precautionary in my design.

Thanks

Steve

Hi Steve,

Let me check if that is possible. Or you can also consider using LM66100.

Hi Steve,

The VOUT pins are connected internally and cannot be used separately.
