SP6003A General Description


The fundamental of SP6003A 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. It also maintains the MOSFET's body diode conduction at minimum level. The SP6003A is capable to adapt in almost all existing flyback converters with few adjustments considered necessary.
