Part Number: LMZ13610
Other Parts Discussed in Thread: BQ24610

Hi,

we are using LMZ13610 in our board to 5V conversion.
The input is 12V from adapter or 7.4V from a battery.
BQ24610 is using for power path control and battery charging.
When the battery voltage is around 7.4V, If we remove the AC or connect the AC, the regulator will restart.

Why this is happening?
In the above scenario, we are taking only 3.5A max from the regulator.

Please suggest.

Hi Shafeeq,

Can you provide your system schematic and also a scopes waveform of both VIN (adapter and battery), VOUT, and EN?

When you say the regulator will restart, do you mean power cycle and return back to regulation or is it stuck in a restart mode?

Jimmy
