TLV61047: 3.7 - 4.2V lithium battery voltage boost conversion

Part Number: TLV61047

Dear Engineer

I need a chip that can boost 3.7-4.2V lithium batteries to a higher voltage. Currently, I'm using the TLV61047DDCR to boost to 12V or 6V, but I feel there is a significant loss. Are there any more suitable models with higher efficiency and lower static current? More suitable for lithium batteries;

best,
