The Brown-- Out circuitry (BO) offers a way to protect the
resonant converter from low DC input voltages. Below a
given level, the controller blocks the output pulses, above

Figure 44, offers a way to observe the high-- voltage (HV)
rail. A resistive divider made of Rupper and Rlower, brings
a portion of the HV rail on pin 5. Below the turn-- on level,
the 26.5 m A current source IBO is off. Therefore, the
