📰00Custom E-ink driver board (UC8252c). Charge pump not starting: PWM is active, but MOSFET Drain is stuck at 3.3V.Reddit r/embedded·u/Sasu-X·about 1 month ago#So4hvGPc#uc8252c#pump#mosfet#high#charge#article+2 more🧰Tag tools✨Add tagHi everyone, I'm designing a custom driver board for a 2.13" E-ink display (controller UC8252c) driven by an RP2040 Zero via SPI. The digital logic seems to work perfectly, but the high-voltage DC-DC booster (charge pump) refuses to start.… Read more15s0Read later0Read More
