REFERENCE DESIGN CIRCUITS
Half Bridge Converter
The MP18024 drives the MOSFETS with
alternating signals (with dead time) in half-bridge
converter topology. Therefore, from the PWM
controller drives INH and INL with alternating
signals The input voltage can go up to 100V.
Figure 4—Half Bridge Converter
Two-Switch Forward Converter
In two-switch forward converter topology, both
MOSFETs are turned on and off simultaneously.
The input signal (INH and INL) comes from a
PWM controller that senses the output voltage
(and output current during current-mode control).
The Schottky diodes clamp the reverse swing of
the power transformer and must be rated for the
input voltage. The input voltage can go up to
100V.

Active-Clamp Forward Converter
In active-clamp–forward converter topology, the
MP18024 drives the MOSFETs with alternating
signals. The high-side MOSFET, in conjunction
with Creset, is used to reset the power
transformer in a lossless manner.
This topology lends itself well to run at duty
cycles exceeding 50%. The device may not be
able to run at 100V with this topology.
