Power supply
6.2
RECTIFIER AND FILTER CKT
The 90Vac-265Vac input line voltage is rectified by D901- D904, and smoothed by C906 to provide
DC operating voltage for the circuit.
6.3
FLYBACK AND PWM CKT
When power is initially applied to the circuit,C909 charges through R903, Q902.When the voltage
across C909 reaches a level of 16V, U901 is enabled, turning on Q901 and turning off Q902 to
complete start-up action.
