Highest-efficiency boost converter recommendation

Hi Sir,

Could you please recommend one or few boost converter chips that fit below requirement?

1. Typical Input: 4.5V

2. Typical Output: 5.5V

3. Channel: Single

4. Rating current: 800mA

5. Efficiency at above conditions: 95% or higher (due to our very limited power budget)

6. Adjustability: Yes

Other features like EN, PG, SW Frequency, package, etc are not critical. The biggest concern is the optimal efficiency.

Thanks in advance!
