BrownOut Protection
The BrownOut 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
it, it authorizes them. The internal circuitry, depicted by
Figure 42, offers a possibility to observe the highvoltage
(HV) rail. A resistive divider made of Rupper and Rlower,
brings a portion of the HV rail on pin 7. Below the turnon
level, a current source IBO is off. Therefore, the turnon
level solely depends on the division ratio brought by the
resistive divider.
