Hi Team,

I am trying to find a buck solution and spec is shown as below.

Input 12V, 1.2A
Output CC/CV : 8V/1.15A~1.28A (cell temp <= 50oC) & 0.128A~0.256A (>50oC)
η>90% and feedback loop should have minimum 10dB gain & 45 degree phase margins.

May I learn from you if we have any solution to promote for customers?

Beginner,

This appears to be some sort of battery charging application, correct? If so, how may cells of what chemistry? If not, what is the application?

Hi Begineer,

Try looking at BQ25611D if you have host processor with I2C communication or BQ25616 if you do not. Both of these chargers have TS pin that connects to battery pack thermistor for changing charge with battery temp. We do not provide feedback loop data as a battery charger has multiple, proprietary feedback loops.

Regards,

Jeff
