APPLICATION IDEAS
In fig. 23 a circuit is suggested to obtain the regulated +3.3V output with a linear configuration instead of the
Magamp circuitry.
In this case the output of the E/A modulates the gate-source voltage of a power MOS in series with the power
stage.
In fig. 24 a simple and cheap latch circuit is showed to manage an OV fault on the Auxiliary output in the same
way of an OC (UV) fault, without having recourse to a (expensive) power crowbar. By tuning the value of RSET
it is possible to set the voltage value that triggers the latch circuit; CDEL defines the turn-on delay. A diode con-
nected between the collector of Q1 and Cout pulls down the output of the auxiliary E/A: this has the same effect
of the OCP_bounce internal signal that guarantees the reduction of duty cycle.
