Need to have dc-dc with input voltage range: 8.1V-12.6V, output: 12V/2A, Non isolated, should be low power as it is battery powered.
Current limit or overload protection is plus. Can u suggest some suitable part for it?

Hi VT,
Thank you for reaching out. This may need a buck-boost circuit as your Vin can be higer or lower than Vout regulation point. You have three options: LM25118, LM34936, or TPS55288.
The LM25118 is a two-switch non-sync buck-boost, and the LM34936 a 4-switch sync buck-boost, and TPS55288 also a 4-switch sync buck-boost but two FETs are integrated. Sync here means synchronous rectifier, which replaces the diode rectifier in the non-sync circuit. The former two devices are already released but the TPS55288 is in engineering sample stage.
Thanks,
