EG1164 High-Power Synchronous-Rectification Boost Module, up to 97 % efficiency, 8–50 V input, 8–60 V adjustable output, >300 W maximum power, 219 kHz switching frequency.
I had some free JLCPCB color-silkscreen coupons lying around so I casually drew a board to try—my first shot at color silkscreen.
My test gear is limited (both supply and load max out at 300 W), so I can’t push it further, but the board should handle four-to-five-hundred watts without breaking a sweat.
I’m still a rookie, so it’s far from perfect; if any pros have suggestions, drop them in the comments and let’s learn together.

EG1164 at a glance
EG1164 is a high-voltage, high-current synchronous boost DC-DC controller. It integrates a reference, oscillator, error amp, cycle-by-cycle current limit, and half-bridge drivers—ideal for high-power jobs. With external HV MOSFETs it can deliver outputs up to 600 V.
- Synchronous boost topology for high-voltage, high-current apps
- One external capacitor sets frequency (0–300 kHz)
- Pin-2 EN resistor programs start/stop thresholds
- UVLO:
– Vcc rising 3.65 V
– Vcc falling 3.60 V - Cycle-by-cycle current limit
- Package: SOP16
