Buck-boost voltage module based on EG1151

I recently bought a new computer that needs PD20V power supply. I am too lazy to use its exclusive power supply which takes up too much space. Because there is a fast charging source on the desktop, but my desktop power supply is a 12V20A power supply, and the voltage is not enough, so I bought something like this to boost the voltage to 24V. Powered by fast charging source.
 
Input voltage 12-28V.
Output voltage 15V, 19V, 24V. Three fixed voltage levels are adjustable.
Output current limit 5A.
 
Measured data:
Input voltage: 12V (board end 11.52V, chip end 11.44V)
Input current: 4.86A
Output voltage: 24V (board end 23.98V)
Output current: 2.2A
Conversion efficiency: 94.2% (board end Terminal efficiency)
Static power consumption: 12V, 0.1A
 
 
Actual testing found that this domestic chip is not ideal, but it is sufficient.
First of all, its switching frequency is only 70K, which is slightly low. Due to the limited volume, the output is barely enough for four 220uf capacitors. The input is 2 220uf.
In addition, an external LDO is required for power supply and the quiescent current is larger.
When increasing 12V to 24V, the static power consumption actually reached 1W. However, the overall efficiency was barely passable. The efficiency is about 93% when outputting 12V to 24V55W.
