EG1164 High-Power Synchronous Rectification Boost Converter Module – Up to 97% Efficiency, Input Voltage 8~50V, Adjustable Output Voltage 8~60V, Maximum Power Over 300 Watts, Switching Frequency 219kHz.
I snagged a free colorful silkscreen voucher from Lichuang and casually designed a board for a test – it's my first time doing a colorful silkscreen.
Due to the limitations of my testing equipment (both the power supply and load are capped at 300W), I wasn't able to test higher power levels. However, this board should easily handle around 400-500 watts or more.
I'm still a beginner, so the design might not be perfect. If any experts have suggestions, please drop a comment below so we can exchange ideas.

EG1164 Introduction
The EG1164 is a high-voltage, high-current boost-type synchronous rectification DC-DC power management chip. It integrates a reference voltage, oscillator, error amplifier, cycle-by-cycle current limiting control, half-bridge driver, and more. This makes it ideal for high-voltage and high-current applications. When paired with an external high-voltage MOSFET, it can support an output voltage of up to 600V.
- Boost synchronous rectification solution, supporting high-voltage and high-current applications
- A single external capacitor can set the operating frequency (0-300KHz)
- Two EN pins allow flexible adjustment of the startup and shutdown voltages with an external resistor
- UVLO (Undervoltage Lockout) feature:
- Startup voltage at the Vcc pin: 3.65V
- Shutdown voltage at the Vcc pin: 3.6V
- Cycle-by-cycle current limiting control
- Package type: SOP16

Load Test with Output
When the input is 12V and the output is 36.6V, the no-load current is 0.11A, resulting in a no-load power of 1.32W.
| Input Voltage | Input Current | Input Power | Output Voltage | Output Current | Output Power | Efficiency |
|---|---|---|---|---|---|---|
| 11.59V | 4.556A | 52.8W | 48.05V | 1A | 48.05W | 91% |
| 11.12V | 9.57A | 106.42W | 47.93V | 2A | 95.86W | 90.1% |

| 31.25V | 8.59A | 268.44W | 59.67V | 4.3A | 256.58W | 95.6% |
| 8.08V | 6.52A | 52.68W | 23.87V | 2A | 47.74W | 90.6% |
| 7.6V | 5.09A | 38.68W | 11.82V | 3A | 35.46W | 91.7% |
| 31.23V | 9.46A | 295.44W | 35.93V | 8A | 287.44W | 97.3% |
Different differences between input and output voltages, as well as varying output currents, will affect the efficiency.
Ripple Test
The method used here to test the ripple might not be ideal—the correct approach would involve using a grounding ring to reduce the ground loop and measuring across the output capacitor. Here, I simply connected directly to the output terminal, so the measured output ripple might appear slightly higher.
- Input 32V, Output 60V (No Load): Ripple peak-to-peak is approximately 77mV.
- Input 32V, Output 60V at 2A: Ripple peak-to-peak is around 412mV.
- Input 12V, Output 24V (No Load): Ripple peak-to-peak is about 30mV.
- Input 12V, Output 24V at 2A: Ripple peak-to-peak is approximately 350mV.
- Input 8V, Output 12V at 2A: Ripple peak-to-peak is roughly 170mV.
