General Descriptions
The AP436 is a high-speed controller designed to
drive N-channel power MOSFET used as
synchronous rectifiers in high current, high
frequency fly-back converters. The circuit does
not require any ties to the primary side and
derives its operating power directly from the
secondary. The circuit functions are structured by
anticipating transformer output transitions then
turns the power MOSFET on or off before the
transitions of the transformer to minimize body
drain diode conduction and reduce associated
losses.
