10 ohm resistor between the LDO and the control transistor (LDO -> resistor -> P-MOS -> cap -> OLED). ~300mV Vpp ripple across the resistor, 30mV to 300mV absolute. That would be 3mA to 30mA That's at 8.4KHz It's not a sine wave; it's 15uS rise and 104uS fall. Voltage at that point is 12.1v with 0.43 Vpp ripple. _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
