Brown- -Out Protection
resonant converter from low DC input voltages. Below a
given level, the controller blocks the output pulses, above
it, it authorizes them. The internal circuitry, depicted by
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 mA current source IBO is off. Therefore, the
turn- - on level solely depends on the division ratio brought
by the resistive divider.
The Brown- - Out circuitry (BO) offers a way to protect the
