DESCRIPTION
The fundamental of APE6019 synchronous rectifier
(SR) driver IC is based on our U.S. patented methods that
utilize the principle of “ prediction ” logic circuit. The IC
deliberates previous cycle timing to control the SR in
present cycle by “ predictive ” algorithm that makes
adjustments to the turn-off time, in order to achieve
maximum efficiency and avoid cross-conduction at the same
time. Due to this patented technology, APE6019 is suitable
for either Forward or Flyback topology.
