7) Resistors RVCC1 and RVCC2 provide the micro-power supply current to VCC and therefore
8) The additional supply components include capacitor CVCC1 for holding up VCC until the charge
9) Resistors RLMP1 and RLMP2 provide the necessary pull-up signal to the LO pin for detecting the
determine the AC line input voltage where the ballast first turns on. The value of these resistors is
determined by:
pump takes over, charge pump capacitor CSNUB for providing VCC supply current, charge pump
diodes DCP1 and DCP2, and limiting resistors RLIM1 and RLIM2 for preventing high currents from
flowing into VCC. These components are typically fixed for most design and are given as:
removal and insertion of the lower lamp filament. Both of these resistor should be high-ohmic to
minimize current flow from VCC and to minimize current flow from the low-side filament to the LO
pin. These resistor values are typically fixed and are given as:
