EG1164 High-Power Synchronous Rectifier Boost Module

 
Overview
The EG1164 is a high-power synchronous rectification Boost power supply module with a maximum efficiency of 97%, an input voltage of 8~50V, an adjustable output voltage of 8~60V, a maximum power of over 300W, and a switching frequency of 219kHz.
I got a free color silkscreen printing coupon from JLCPCB and quickly designed a board to try it out; this is my first time using color silkscreen printing.
Because my testing equipment is limited (both the power supply and load are maximum 300W), I can't test higher power outputs. This board should be able to handle 400-500W or more without problems.
I'm a beginner, so it might not be very well done. Experts, please leave any suggestions in the comments section so we can all learn from each other.
EG1164 Introduction:
The EG1164 is a high-voltage, high-current boost synchronous rectification DC-DC power management chip. It integrates a reference power supply, oscillator, error amplifier, cycle-by-cycle current limiting control, half-bridge driver, and other functions, making it very suitable for high-voltage, high-current applications. With an external high-voltage MOSFET, it can support a maximum power supply voltage output of 600V.


Boost synchronous rectification scheme, supporting high voltage and high current.


An external capacitor allows setting the operating frequency (0-300KHz).


EN pin 2: External resistor allows flexible adjustment of start-up and shutdown voltages.


UVLO: Undervoltage lockout function.

Start-up voltage at
Vcc pin: 3.65V. Shutdown voltage at Vcc pin: 3.6V.



Week-by-week current limiting control.


Package: SOP16.

Different input/output voltage differences and different output currents will affect efficiency.
The ripple test
method below is incorrect. The correct method should be to use a grounding ring to reduce grounding loops, and also to measure the output capacitor terminals. I simply connected it directly to the output terminals to avoid this, so the output ripple measured below may be too high.
With an input of 32V and an output of 60V under no-load, the peak-to-peak ripple is approximately 77mV. With an input of 32V and
an output of 60V at 2A, the peak-to-peak ripple is approximately 412mV. With an
input of 12V and an output of 24V under no-load, the peak-to-peak ripple is approximately 30mV.
With an input of 12V and an output of 24V 2A, the peak-to-peak ripple value is approximately 350mV.
With an input of 8V and an output of 12V 2A, the peak-to-peak ripple value is approximately 170mV.
