FIGURE 18D. CONVENTIONAL PUSH-PULL
Full Bridge and Current Doubler - No center tap is
required. The secondary winding carries half of the load, i.e.,
only half of the load is reflected to the primary.
Conventional Full Bridge - Center tap is required on the
secondary side, and no center tap is required on the primary
side. The secondary winding carries all the load. i.e., all the
load is reflected to the primary.
Push-Pull and Current Doubler - Center tap is required on
the primary side, and no center tap is required on the
secondary side. The secondary winding carries half of the
load, i.e., only half of the load is reflected to the primary.
Conventional Push-Pull - Both primary and secondary
sides require center taps. The secondary winding carries all
the load, i.e., all the load is reflected to the primary.

? Input UV lockout
The Integrated Solution is much simpler than a discrete
solution. Over-temperature protection and input under
voltage lockout can be added for better system protection
and performance.
The Discrete Solution requires a significant number of
components to implement the features that the ISL6550 can
provide.
