EG1164 High Power Synchronous Rectifier Boost Power Supply Module, Maximum Efficiency 97%, Input Voltage 8~50V, Output Voltage 8~60V Adjustable, Maximum Power 300W or more, Switching Frequency 219kHz.
Because I have limited test equipment (power supply and load are maximum 300W), so I can not measure the higher power, this board should not be a problem with a maximum power of more than 400 or 500 watts.

EG1164 Introduction
The EG1164 is a high-voltage, high-current step-up synchronous rectifier DC-DC power management chip with an internal integrated reference power supply, oscillator, error amplifier, cycle-by-cycle current limiting control, half-bridge driver, etc. It is very suitable for high-voltage and high-current applications, and it can support up to 600V power supply voltage output with an external high-voltage MOS tube.
Boost synchronous rectification solution, support high voltage and high current solutions
An external capacitor can be used to set the operating frequency (0-300KHz).
2-pin EN external resistor for flexible adjustment of start-up and shutdown voltage.
UVLO undervoltage lockout function:
Vcc pin turn-on voltage 3.65V
Vcc pin OFF voltage 3.6V
Week-by-week current limit control
Package: SOP16
