I see that there are chips available for power banks, SOC kind of things such as IP5318, what i am looking for is a good efficiency boost converter IC that can do from 3V at the lowest to 12v 1.5A, or 18W sustained at no less than 88% efficiency. TPS61088 is one chip but are there other chips please suggest. Ideally do not want to use power bank soc but need ic that has similar boost feature
