TPS61021A: Low quiescent current DC-DC converters

Hi Karpagadevi,

I'm sorry that I don't understand 'either or both (3.2V to 3.3V and 3.8V) and (3.2V to 1.8V)'. Can you chare Vin range and Vout target? 

Best Regards,

Travis

Hi Travis,

I need Part numbers for the DC-DC Converter with 1A output current and low quiescent current and

Input voltage range: 1.5V to 4V

Output Voltage range: 1.5V to 4V 

We are using the converter to convert voltage from

3.2V to 3.3V

3.2V to 3.8V

3.2V to 1.8V

With Regards,

Hi Karpagadevi,

I am little confused, from your detailed application info, seems your  input voltage is 3.2V only, but in your requirments, there is a big range? why and which is correct?

Recommend our TPS631000/TPS631010/TPS631011 for your application. altough it can not absolutly meet your input voltage range.

Hi Tao,

We are using a battery to power the DC-DC converter, which operates within a voltage range of 2V to 3.8V. Therefore, we require a DC-DC converter that supports an input voltage range of 2V to 3.8V with High efficiency and low quiescent current.

Hi Karpagadevi,

Ok, it is clear here.

Recommend device mentioned above. thanks.

Hi Tao,

Could you provide few more part numbers that would meet our requirements?

Hi Tao,

Could you provide few more part numbers with Low quiescent current?

Hi Karpagadevi,

I am afraid TPS6310XX series is our lowest quiescent current device for your application. 

Other option should be TPS6380X family. TPS63805/6/7.

Hi Tao

Okay thanks.

Could you please provide the part number for Boost converter for our requirements.

Is it possible to get low quiescent current in this case

Hi Karpagadevi,

Please look at TPS61299 family. The TPS612997 in TPS61299 family will be availible.

But step down operation is not supported for boost devices. Vout has to be higher than Vin.

Best Regards,

Travis
