I am looking for a buck boost converter able to support some current peaks ( up to 2.7A at 3.3V for example) required for powering a GSM/GPRS module.
Vin is from 1.8V to 5.5V.
Iout = 1.5A.
Do you have some products which can fit ?
Unfortunately we do not currently have a buck-boost that is capable of delivering 1.5A from 1.8V.
It could be done with a boost regulator such as the ADP1614 charging a large enough cap and followed by a buck regulator like the ADP2119.
The only buck-boost currently available is the ADP2504 (1A capable)
